Solve the system by substitution.

1 answer:

3 0

Answer:

I gave you most of the answer. I'll let you check my work and find the point using the solution.

Step-by-step explanation:

The first thing we do is we divide by negative one in the first equation to get

y = -x.

-3x + 3y = -36

Plug in y = -x and get

-3x + 3(-x) = -36

= -3x - 3x = -36

This equals -6x = -36

divide both sides by -6 and you get 6. 6 is your x value

Plug 6 back in to the second equation.

-3x + 3y = -36

-3(6) + 3y = -36

-18 + 3y = -36

3y = -18

y = -6

Answer:

$y=2x+4$

Step-by-step explanation:

Given a slope and a point on the line, you can use point slope form and then rearrage your terms into slope-intercept form

SLOPE-INTERCEPT FORM: $y=mx+b$ , where "m" is your slope and "b" is your y-intercept
POINT-SLOPE FORM: $(y-y_{1}) =m(x-x_{1})$ , where $y_{1}$ represents the y-coordinate of your point, $x_{1}$ represents the x-coordinate of your point, and $m$ represents the slope
