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

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

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
