solomonzelman · Answer

But you know that this is a point slope form.
$\large\color{black}{   (y-y_1)=m(x-x_1)   }$
where the point is (x1,y1) and m is the slope.

anonymous · Answer

I have to fill in the blank, which is where the question marks are.

solomonzelman · Answer

Lets visualize the slope.
lets look at a change in x.
when x is 1, the y is -2.
when x is 2, the y is 2.
So the slope is 4.

solomonzelman · Answer

So, when slope is 4, and the point is (1,-2)
fill in blanks.

$\large\color{black}{   (y-(-2)~~)=4(x-(1)~~)   }$

Just another  a-(-b) = a+b    to finish the problem.
