Question

What is the equation of the line through the origin and (-4,-9)

Answer 1

Answer:

y = 9/4x

Step-by-step explanation:

First we need to find the slope

m = (y2-y1)/(x2-x1)

    = (-9-0)/(-4-0)

    = -9/-4

    =9/4

We know the y intercept is 0 since it goes through the origin

We can use the slope intercept form of the equation

y = mx+b

y = 9/4 x +0

y = 9/4x
