You can
put this solution on YOUR website!For this type of problem, you first make the slope into a fraction. Like this

Now, the 2/1 equals the numerator on the other side, you put y - (the y). So for this problem it would be

.
And for the denominator (for the other fraction), you put x- (the x). Again, it would be

So your equation should look like
Now you multiply the denominator (of the right side) by the left side, as shown below.

which simplifies to
And all you have to do now is add or subtract the number next to y. So that would look like

which simplifies to
and that's your answer!
