--- Sam

--- Tim

Step-by-step explanation:

Given

Sam                         Tim

х  --- f(x) ---------------  g(x)

1  --- 80   --------------- 100

2  --- 110  --------------- 120

3  --- 140 --------------- 140

4 --- 170 -------------- 160

Required

Determine the y value

y value implies the equation of the table

Calculating the equation of Sam

First, we need to take any corresponding values of x and y

Next, we calculate the slope (m)

Next, we calculate the line equation using:

Make y the subject

Calculating the equation of Tim

First, we need to take any corresponding values of x and y

Next, we calculate the slope (m)

Next, we calculate the line equation using:

Make y the subject

squares, rhombus, rectangles

.25
