Answer:
Formula
Slope of a line
Once your equation is in slope-intercept form: "y = mx+b", the coefficient of "x" (the "m") is the slope. The constant (the "b") is the y-intercept at (0, b).
Step-by-step explanation:
slope= dy/dx
=y2-y1/x2-x1
Please Help I can’t figure out 4
The question is down below and I would really appreciate the help!
Answer:
y = 3x
Step-by-step explanation:
from the table slope or rate of change is
m = 6 - 0 / 2 - 0 = 6/2 = 3
m = 12 - 6 / 4 - 2 = 6/2 = 3
m = 18 - 12 / 6 - 4 = 6/2 = 3
so m = 3
y = mx + c
c is y intercept --> y value when x is 0
y = 0 = c
so line equation is y = 3x + 0
y = 3x
Answer:
B, or 3x.
Step-by-step explanation:
When looking at the x value (time), and the y value (distance), you can see that every time you multiply the x value by 3, you get the y value.
2 x 3 = 6
4 x 3 = 12
6 x 3 = 18
Therefore, your answer is 3x.

In your own words, explain to me what is absolute value? Make sure to talk about the definition of it, how you find it, and how it's different from just plotting an integer on a number line. You must provide 3 sentences or more.
Answer:
It's a function that associates a real number x with a positive real number using the flowing definition: If the number is not negative (so either positive or 0) the absolute value is x. If x is negative, the absolute value is -x.
This means that to find the absolute value of x you must first determine if x is negative or not, and if it is, multiply it by -1. If it isn't, leave it as it is.
Since the absolute value is a function (of a given number), you can't just plot that number in the number line but the function (so in this case absolute value must be taken first.
The absolute value of x is never negative, so given the absolute value of x we can't determinate if x was positive or negative (if x =/ 0) before the absolute value was taken.
