Referring to the figure

find m∠5

∠4 = 30° (Corresponding angles)

∠4 + ∠5 = 180° (Linear Pair)

30° + ∠5 = 180°

∠5 = 180° - 30°

∠5 = 150°

slope intercept form looks like:

y = mx + c

Lets rearrange

-10x + 11y = -6

+ 10x to both sides

11y = 10x - 6

Divide both sides by 11

y = 10/11 x - 6/11

The slope is 10/11

The y intercept is -6/11
