Solution
For this case we can find the slope with this formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}=\frac{-13+25}{-3+6}=\frac{12}{3}=4[/tex]
then the slope is m =4
Now we can find the intercept on this case like this:
We can select the poitn (x= -6, y= -25)
-25= 4(-6)+b
b= -25 +24= -1
Then the correct option is:
y= 4x -1
