Question

Find the slope and y-intercept

and write the equation.
(-98, 22), (0, -48)
m =
b=

Answer 1

m = -35/49

c = -48

y = -35/49 x - 48

Explanation:

Given the coordinate point

(-98, 22), (0, -48)

Slope m = y2-y1/x2-x1

m = -48 - 22/0 -(-98)

m = -70/98

m = -35/49

Substitute m = -35/49 and (0, -48) into the equation y = mx+c

-48 = 0(-35/49) + c

-48 = c

c = -48

Hence the y-intercept is -48

Get the equation

Recall that y = mx+c

y = -35/49 x - 48
