Answer:

4

Step-by-step explanation:

find the equation of the line:

slope = rise / run

rise is 20, run is 8

20/8 = 5/2

slope intercept form is y = mx + b

where m is slope and b is y int

y = 5/2(x) + b

use a point given to find b

44 = 5/2(16) + b

44 = 40 + b

b = 4

Answer:

[see explanation and graphs]

Step-by-step explanation:

Going by the slope, which is 5/2, your y-intercept would be 4.

[tex]m=\frac{64-44}{24-16} =\frac{20}{8} =\frac{5}{2}[/tex]
