Systems of Equations, Slope, Slope-Intercept Form, Writing Equations of Lines

Solve the system by substitution.

Enter your answer as a coordinate point with NO spaces (x,y)

y = 2x + 6

2x - y = 2

What is the y-intercept of this graph?

• 1
• -2
• 0
• 3

Don't forget. You can plot both on the graph and find the intersection. You only need X. (a)  

• A

• B

• C

• D

You can put both on the graph and find the intersection.

• A

• B

• C

• D

Find the slopes and y-intercepts first. Put each line in slope-intercept form. (a)
