Question

Write the equation of the line, in slope-intercept form, that contains the points (-1, -2) and (1, 2).

Answer 1

what did you get for the slope?

Answer 2

2

Answer 3

yes !

Answer 4

so now what?

Answer 5

That's why I'm asking..lol

Answer 6

do you know the point slope formula?

Answer 7

y=mx+b

Answer 9

ok so were just gonna do the same thing we did a minute go:

y-y1=m(x-x1)............... (y1 is your y intercept, m is your slope, x1 is your x intercept)

so you have a slope of 2, your first y intercept is -2, and your first x intercept is -1, now just substitute those into the point-slope equation

y- (-2) = 2(x- (-1) now rewrite it -->

y+2= 2(x+1) now distribute -->

y+2= 2*x + 2*1 now rewrite again -->

y+2= 2x +2 subtract "2" from the "y" side, what you do on one side, do to the other
-2 -2

y= 2x (this is now in slope- intercept form or y=mx+b)
