Question

What is the equation of the following line written in slope-intercept form?

y = -5x
y = 5x
y = 5/x

Answer 1

y=5x

Explanation:

first, we know that a rising line's slope is always positive, so the first one is incorrect

let's figure out the slope: y-y'/x-x' is the formula.

now, -5-5/-1-1= -10/-2= 5. so the slope of this line is 5.

Answer 2

The equation is y=5x
