1. PLOT ANY POINT
Solutions
To Linear
Equations

2. Interpret the equation y = mx + b as defining a linear function.
COMMON CORE #13(Part 2)
Interpret the equation y = mx + b as defining a linear function.
We will be graphing two equations on each slide and find the solution of those two linear equations.

3. y = 3x – y = x + 2
(3, 5)

4. y = 3x y = 4x
(2, 8)

5. y = -4x y = -4x + 8
parallel or no solution

6. y = 2x y = 4x - 2
(1.5, 4)

7. y = 2x – 1 y = -4x + 11
(2, 3)

8. y = x y = 2x + 8
Infinite
Solutions

9. y = ⅔x + 7/3 y = -2x + 5
(1, 3)

10. PRACTICE PROBLEMS
