I just need the formula. I cant find it anywhere.

Do you know how to calculate the rate of change?

anonymous · Answer

Use $ y - y_1 = m(x - x_1)  $  and then turn it into point slope form

marihelenh · Answer

$$\frac{ y _{2}-y _{1} }{ x _{2}-x _{1} }$$ will give you the slope, and then use the formula @Nixy gave you.

anonymous · Answer

You can get the slope with $  \huge m = \frac{y_2-y_1}{x_2 - x_1} $
