Use the slope formula to find the slope between (4, 9) and (1, 6)

1

Step-by-step explanation:

I believe it is 1 because when you use the rise over run slope formula aka

y2-y1/x2-x1 and put it into a calculator like desmos, you get one.

if your equation is in the form ax2 + bx + c, you can find the maximum by using the equation:

max = c - (b2 / 4a).

the first step is to determine whether your equation gives a maximum or minimum.

-x2 + 4x - 2.     thats an example hope it
