To find the rate of change, we need to calculate the change in the y-coordinate divided by the change in the x-coordinate for any two points. Let's consider the first two points: (-2, 80) and (-1, 70).
Change in y-coordinate: 70 - 80 = -10
Change in x-coordinate: -1 - (-2) = 1
Rate of change = (-10) / 1 = -10
Therefore, the rate of change for these two points is -10.
(-2, 80)
(-1, 70)
(2, 40)
(5,10)
what is the rate of change?

ok, what is the y intercept?
To find the y-intercept, we need to identify the value of y when x is equal to 0. None of the given points have an x-coordinate of 0, so we cannot directly determine the y-intercept from the given data.
