Graph each equation using slope-intercept form.

y = x + 7

1.

2y = (1/2)x - 6

2.

y = -2y + 5x = -8

3.

-6y + 5x = -8

4.

x = 9y + 5

5.

8x = -2y - 4

6.

Determine which of the following lines are parallel to each other.

a) (1/5)y + (8/5) = x b) 4y = 5x + 24 c) -4(3y + x) = -84 d) 3y + x = -9 e) (1/3)(-y + 5x) = 2 f) (7/2)y + x = 31.5 g) y - (1/2) = (-2/7)x h) y + 5 = (5/4)x
