Solve the system of equations by graphing, put in slope-intercept form first:

x = 2y

4x + 2y = 15

• no solution

• infinitely many solutions

• one solution (3, 1.5)

• one solution (3, 6)

Solve the system of equations by graphing, put in slope-intercept form first:

x = 7 - 2y

2x + y = 5

• (-1,4)

• (4,-1)

• (1,3)

• (3,1)
