the rate of change for the interval shown in the table is a. constant or b. non constant, so the function is an a. linear or b. non linear

Each time x goes up by 1, y also goes up by 1 as well.

slope = rise/run = 1/1 = 1

Or we can use the slope formula to get

m = (y2-y1)/(x2-x1) = (3-2)/(2-1) = 1/1 = 1

I used the first two rows as the points to plug into the slope formula.

You can pick any two rows you want and you'll get the same slope value.

--------------------------------------

Because we get the same result of 1 each time, this means the rate of change is constant and this function is linear. Plotting all four points will show a single straight line goes through all of them. See diagram below.

b) 36

18 times 2 is 36
