Answer:

-3

Step-by-step explanation:

Isolate -3y by subtracting x from both sides

-3y = -18 - x

Divide everything by -3

y = 6 + 1/3x

Slope is 1/3, and perpendicular lines have the reverse reciprocal slope, so our slope is -3

It is x is less than or equal to -7.
First you subtract -10 from both sides so you will get -2x is greater than or equal to 14 then you divide -2 from both sides so if you multiply or divide a negative number you flip the signs so x is less than or equal to -7.
