So you want to make one of the equations equal to one of the placeholders exg y=x+3

so we have
x+y=2 and
-2x+y=2

I chose to make -2x+y=2 equal to y so
-2x+y=2
add 2x to both sides
y=2+2x

subsitute 2+2x for y in x+y=2
x+2+2x=2
add like terms
3x+2=2
subtract 2 from both sides
3x=0
x=0

subsitute x=0 in x+y=2
0+y=2
y=2

x=0
y=2

Answer:

Slope: 3

Y-intercept: 1

Step-by-step explanation:

This equation is written in slope-intercept form of Y=MX+B. The M is the slope and the B is the y-intercept. The M in this equation is 3. And the B is the 1.
