Answer:
A
Step-by-step explanation:
Given the 2 equations
x = 3 - y → (1)
5x - 12 = y → (2)
Substitute x = 3 - y into (2)
5(3 - y) - 12 = y ← distribute and simplify left side
15 - 5y - 12 = y
3 - 5y = y ( add 5y to both sides )
3 = 6y ( divide both sides by 6 )
= y, that is
y = 0.5 → A
The last one

: <span> you have to solve for y. So if you do that you get y= -2/3x + 6
graph according to y=mx + b
b is y intercept, so the graph crosses the point (0, 6)
m is the slope and slope is rise over run. So go down 2 and right 3 from (0,6) as many times as you need to fill up the graph.
Then go up 2 and left 3 from (0,6) as many times as you need to fill the graph.
Put arrows at each end of your line to show that it's a line. </span>
