Answer:
y = -3x - 2
Step-by-step explanation:
Given the coordinates (-2, 4) and (-1, 1), we are to find the equation of a line passing through the points.
The standard form of the equation is expressed as;
y = mx+c
m is the slope
m = y2-y1/x2-x1
m = 1-4/-1+2
m = -3/1
m = -3
get the y-intercept c;
Substitute m = -3 and any point say (-1,1) into the equation y = mx+c
1 = -3(-1) + c
1 = 3 + c
c = 1-3
c = -2
Get the required equation;
y = mx+c
y = -3x + (-2)
y = -3x - 2

In a graph, the initial value of a functions is the _____.
Answer:
Initial value of a graph is always the variable a.
Step-by-step explanation:
If you have any questions about that, let me know :)
Answer:
The initial value, or y-intercept, is the output value when the input of a linear function is zero. It is the y-value of the point where the line crosses the y-axis. An increasing linear function results in a graph that slants upward from left to right and has a positive slope.

find the midpoint of the segment with the following endpoints. (8,10) and (1,4) ?
I NEED HELP PLEASEE ASAP
Answer:
-5 and initial value is -1
Step-by-step explanation:
Slope= y2-y1/x-x1
-11-(-1)/2-0
-10/2
-5
Initial value is y-intercept where x is 0 (0,y)
so
(0,-1) is starting point

-6y+17=3y-10 solve this equation
Answer:
y=3
Step-by-step explanation:
Step 1: Subtract 3y from both sides.
−6y+17−3y=3y−10−3y
−9y+17=−10
Step 2: Subtract 17 from both sides.
−9y+17−17=−10−17
−9y=−27
Step 3: Divide both sides by -9.
−9y
−9
=
−27
−9
Answer:
The answer is Y=3
Step-by-step explanation:
when you get all the varibles together and subtract from both side you'll be left with -9y+17=-10 so to get 17 to the other side you have to do the inverse operation and that would be to subtract.This means you have to subtract to both side 17-17 would cancel out and -10-17 would be -27.
Finally in order to get Y alone you once again have to do the inverse operation and the inverse of multiplying is dividing so -27/-9 would be positive 3. So Y=3

A fair number cube is rolled and then rolled again. Which statement
represents the probability of rolling an odd number and then rolling
another odd number? *
Step-by-step explanation:
Everytime the dice is rolled, there is a 50% chance to get an odd number.
Hence 50% * 50% = 25%.
Tom has $60 dollars. He spends $7 for lunch each day. Which equation
shows how much money c he has left after d days?
D. None of these
A. c = 60 + 7d
B. = 60 - 7d
C. = 60 - 75
B seems like the corrects answer because wen dont know how many days and he has 60 dollars
Answer:
B
Step-by-step explanation:
7d is how much money he spends on lunch in all
then you need to subtract from 60 because that is the total amount of money he has
The graph of a function is shown:
scatter plot of the points negative 5, 4 and negative 2, negative 1 and negative 1, 3 and 4, negative 3
Which of the following correctly identifies the set of outputs?
{–3, –1, 3, 4}
{–5, –2, –1, 4}
{(–5, 4), (–2, –1), (–1, 3), (4, –3)}
{(4, –5), (–1, –2), (3, –1), (4, –3)}
Answer:
The correct option is:
[tex]\left\{\left(-5,\:4\right),\:\left(-2,\:-1\right),\:\left(-1,\:3\right),\:\left(4,\:-3\right)\right\}[/tex]
Step-by-step explanation:
There are 4 points that have been scattered on the coordinate plane.
It is clear from the coordinate plane, that those points are located as explained below.
at x=-5, y=4
so the point (-5, 4) is on the coordinate plane.at x=-2, y=-1
so the point (-2, -1) is on the coordinate plane.at x=-1, y=3
so the point (-1, 3) is on the coordinate plane.at x=4, y=-3
so the point (4, -3) is on the coordinate plane.Therefore, the correct option is:
[tex]\left\{\left(-5,\:4\right),\:\left(-2,\:-1\right),\:\left(-1,\:3\right),\:\left(4,\:-3\right)\right\}[/tex]

171 /6
171/6 = 28.5
Michael baked 60 oatmeal cookies and 45 chocolate chip cookies to package in plastic containers for her friends at school. She wants to divide the cookies into identical containers so that each container has the same number of each kind of cookie. If she wants each container to have the greatestnumber of cookies possible, how many plastic containers does she need?
(I really need help)
Answer:
3
Step-by-step explanation:
Michael must find the smallest number possible that can divide 60 and 45 then take the two quotients after dividing the 2 types of cookies by the smallest number possible.
2 is not possible as 45 is an odd number
3 can divide both 60 and 45
60/3 = 20 oatmeal cookies in each container.
45/3 = 15 chocolate chip cookies in each container.

Item 7 Question 1 Select the equation that represents the question. What percent of 300 is 51? 300=51×p 51=p×300 300=p×51 p=300×51 Question 2 Solve the equation. P= %
Answer:
51 = p×300
p = 17%
Step-by-step explanation:
Let p be the value of the percentage.
To find the percentage;
51/300 = p
51 = p * 300
Therefore, p = 0.17
Percentage represents a 100;
P = 0.17 * 100
P = 17%
