Write an equation of the line that passes through (-2, -4) and (-4, 2)

Question

okay, well you have 2 points...the first thing you should do...is find the slope of the line

your 2 points are (-2, -4) and (-4,2)

so

(-2, -4) and (-4,2)
(x1, y1)        (x2, y2)

use this equation to find slope

$$m = \frac{ y2 - y1 }{ x2 - x1 }$$

I have labeled them for you...so your slope is...?

-6/2

yes....so your slope....you can plug into this equation...along with either one of your points you have (pick your favorite :D) 

y = mx + b

so pick your point...(x,y) and plug those numbers in for x and for y in this equation
then plug your slope in for 'm' in this equation...this will solve for 'b' (your y-intercept)

what does your equation look like?
