Solve the following pairs of linear equations by graphing. Confirm the solution using algebra.
y = 3x — 2 and y x
Intersection at (1, 1)
x=1
y=1

Solution using algebra
Standard form: Equations are already in standard form
Combining the equations: 3x 2 = x
2x = 2
x — 1
Substituting into eq 1 y = 3(1) 2
y= 1
Check substituting into cq2 y = 1
Solution: x = 1, y = 1
