Finding the slope of the given line
We need to find the slope of this equation to find the slope of a line perpendicular to it. This means we must solve for y.
Start off by subtracting 8x from both sides of the equation to start isolating the variable y.
Now solve for y by dividing both sides of the equation by -7.
This can be broken into two parts by distributing the negative sign from the -7 into the 9 and -8x like so:
The slope of a line is the coefficient of x, so in this case the slope of the given line () is
.
Finding the slope of a line perpendicular to the given line
Two lines that are perpendicular would have opposite reciprocal slopes, which means the perpendicular slope would be the negative counterpart and would be flipped.
For example, if you have 2 as the slope of one of the perpendicular lines, the other line would be the opposite (-2) reciprocal ().
Therefore, since we have the slope of one of the perpendicular lines (the given line), we would find the opposite reciprocal of it's slope to solve this problem.

- Opposite:
- Reciprocal:

12x−5y=−20
y=x+4
Answers
Answer:
12x-5(x+4)=-20
7x=0
x=0
so,y=4
x=0
STEP BY STEP EXPLANATION:
1.) 12x-5y=-20
y=x+4
2.) 12x-5(x+4)=-20
*because you are taking the y= equation and putting that into 5y replacing the y.
3.) 12x-5x-20=-20
*because you multiply -5 by the x and the 4 and get -5x-20.
4.) 7x-20=-20
*because you subtract 5x from 12x because you are using like terms to make the equation smaller.
5.) 7x=0
*because you add the 20 on both sides to cancel out the 20 to get x closer to being by itself.
6.) x=0
*because you divide 7 on both sides to get x completely by itself.
