Question

What is the solution to the system of equations below? Y=-4/5x-6 & y=-30

Answer 1

its A) 45,-30

i got this answer by using a graphing calculator.

Answer 2

So when you are trying to find the solution to the system of equations make sure that you have it where y= -4/5x-6 and y= -30 are written like this:

-30=-4/5x-6

And then solve for x:

Add 6 on both sides. 

-24=-4/5x

Then multiply by the reciprocal of -4/5.

-5/4*-24=-5/4*-4/5x

x=30 

But then you are gonna want to plug 30 in for x in y=-4/5x-6 to make sure that it is the same as y=-30.
