Question

What is the rate of change and initial value for the linear relation that includes the points shown in the table?

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
