4.2: Slope-Intercept Form: Determine the slope by using the equation. 19.(3,7) (5,10)

20.(1,5) (2,8)

19.3/2

20.3

Step-by-step explanation:

the slope is simply the gradient given by the formula

m=y2-y1 /x2-x1

for 19. y2 is 10,y1 is 7,x2 is 5 and x1 is 3 therefore the gradient is

m=10-7/5-3

=3/2 or 1.5

for 20 the gradient is

m=8-5/2-1

=3/1

=3
