Answer: it’s 81
Step-by-step explanation:
easy math I know it’s 81
Factor out like terms
-y(7+y)=0

The coefficient of x is the slope of the line , So the slope of the above equation is -3 .
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
Remember from now on ,
Product of multiplying the slopes of two lines which are perpendicular to each other , is -1 .
Thus ;

m is the slope of the line which we want.

Negatives simplifies

Divide sides by 3

We have following equation to find the point-slope form of the linear functions :

x(0) and y(0) are the coordinates of the point which the line passed through.


Add sides 8

Done....
