Question

What is the rate of change and initial value for the linear relation that includes the points shown in the table?
x y
1 10
2 8
3 6
4 4
Initial value: 12, rate of change: −2
Initial value: 8, rate of change: 2
Initial value: 12, rate of change: 2
Initial value 8, rate of change: −2

Answer 1

x   1 2 3
y 10 8 6
So find the slope m:  (6-10)/(3-1) = -4/2 = -2
Going backwards when x = 0, y will be 12 (you can see this)
So
Initial value: 12, rate of change: −2
