Question

Find the equation in slope-intercept form that passes through the points (9, 3) and (19, -17).

Answer 1

y=-2x+21

Explanation:

use y2-y1/x2-x1 to find the slope so= -17-3/19-9=-20/10=-2

so once you find the slope take one of the points and plug it into the slope-int equation so... if you take (9,3) and take your slope (-2) so it would be: 3=-2(9)+b solve for b to get 21=b as your int. so.. y=-2x+21
