Question 178212
First, find the slope from:
m = (y2-y1)/(x2-x1)
Given:(-3,7)and (5,-1)
.
m = (-1-7)/(5-(-3))
m = (-8)/(5+3)
m = (-8)/(8)
m = -1
.
Now, using the slope (-1) above and one of the two given points say (-3,7) plug it into the point slop form of:
(y-y1) = m(x-x1)
(y-7) = (-1)(x-(-3))
(y-7) = (-1)(x+3)
y-7 = -x-3
y = -x + 4 (this is what they're looking for in "slope intercept" form)
