The answer is B. The angle next to 100 degrees would be 80 as the angles are supplementary. Then you would add 80 + 70 = 150. All the angles in a triangle add to 180, thus making the "x" angle 30 due to 180 - 150.
Hope this helped :))
The slope is zero because the rise (8-8) is zero, and the line will be horizontal because lines with a slope of zero are horizontal.
Im pretty sure its 3x + 1
