3. y = 2x + 1 Rise Run 2 1 slope y-intercept b = 1 m = 2 y = 2x + 1 Jeff Bivin -- LZHS

4. y = -3x + 2 Rise Run -3 1 slope y-intercept b = 2 m = -3 y = -3x + 2 Jeff Bivin -- LZHS

5. Rise Run 2 3 slope y-intercept b = -1 Jeff Bivin -- LZHS

6. Rise Run 2 slope y-intercept b = 3 Jeff Bivin -- LZHS

8. 2x + 3y = 5 x-intercept 2x + 3(0) = 5 2x + 0 = 5 2x = 5 y-intercept 2(0) + 3y = 5 0 + 3y = 5 3y = 5 Jeff Bivin -- LZHS

9. 4x - y = 6 x-intercept 4x - (0) = 6 4x - 0 = 6 4x = 6 y-intercept 4(0) - y = 6 0 - y = 6 -y = 6 Jeff Bivin -- LZHS

10. 4x + 2y = 3 x-intercept 4x + 2(0) = 3 4x + 0 = 3 4x = 3 y-intercept 4(0) + 2y = 3 0 + 2y = 3 2y = 3 Jeff Bivin -- LZHS

11. 3x - 2y = 7 x-intercept 3x - 2(0) = 7 3x - 0 = 7 3x = 7 y-intercept 3(0) - 2y = 7 0 - 2y = 7 -2y = 7 Jeff Bivin -- LZHS
