Question

What is the result of subtracting the second equation from the first?

x - 3 y = 6

-8x - y = 6

Answer 1

Step-by-step explanation:

x - 3y = 6 and y = 3x + 2

The second equation is in the format of...

y=mx+b, m is the slope.

Let's convert the first equation...

x - 3y = 6

Let's subtract x from both sides...

-x+x-3y=-x+6

-3y=-x+6

Let's divide both sides by -3...

(-3y)/-3=(-x+6)/-3

A negative number divided by a negative number results in a positive number.

y=(1/3)x-2
