SOLUTION: USE FUNCTION NOTATION TO WRITE AN EQUATION FOR THE LINE CONTAINING THE POINTS (-2,7) AND (3,-5).

You can put this solution on YOUR website!
From the given points, we can calsulate the slope.
That is, the difference in y ocer the difference in x.



The slope is

And we can plug in the slope along with one of the given coordinate sets into the point-slope formula in order to get the equation for the line.

(y - 7) = ( x - (-2) )

(y - 7) = x

y = x +

But since this is to be in function notation:

f(x) = x +
