Write the equation of the line passing through (2,0) and (0,-5)​

Answers

Answer:

y=5/2x+2

Step-by-step explanation:

To get the slope,

(-5-0) /(0-2)=-5/-2=5/2

Introduce points (x,y) (0,2) i.e one of the given points ,it should give same answer either way

(0,2)(x,y)

y-2/x-0=5/2

Cross multiplication,2(y-2)=5(x-0)

2y-4=5x-0

2y=5x-0+4

2y=5x +4

Divide both sides by 2 to get

y=5/2x+2.

Answer:

Assuming the x-6 is under the square root sign, the value must be greater than 6 because you can not have 0 in the domain. That narrows it down to either B or C but since the denominator can not be anything less than 0, your answers will always be positive so that means the answer is Its domain is (6,∞)

what is the equation of the line in slope-intercept form?

Answers

Answer:

y = 8x

Step-by-step explanation:

Slope intercept form is y = mx + b

y = y coordinate

m = slope, rise over run

x = x coordinate

b = y-intercept, where the line crosses the y-axis.

y = mx + b

y = 80/10x + 0

y = 8x + 0

y = 8x

Answer:

y=-8x
