Find the slope of the line through the points (5, 4) and (-1, 5).

What is the y-intercept of the line y = 4x – 4

Find the slope of the line through the points (-1, 2) and (9, 7)

Find the slope of the line through the points (5, 5) and (-5, 5)

slope = (5-4)/(-1-5) =1/(-6) =-1/6

y intercept = -4

Slope = (7-2)/(9-(-1))=5/10=1/2

slope (5-5)/(-5-5) =0

Slope (0-3)/(7-4)=-3/3=-1

equationof the line y-3 =(-1)(x-4)

y-3+x-4=0

y+x =7

y =-(1) x+7
