You can put this solution on YOUR website! The first step is to solve for y.
y+4=7(x-7)
distribute the right hand side.
y+4=7x-49
subtract 4 from each side.
y=7x-53
We now know that the slope of the equation is 7.
The slope of a line perpendicular must
be the negative inverse of 7.
Think 7/1 flipped with the sign changed which is -1/7 .
So an example of an equation that is perpendicular
is
