1 answer:

4 0

Vertical angles are equal

7x - 19 = 4x + 2
7x - 4x = 2 + 19
3x = 21
x = 21/3
x = 7

m∠ABC = 4x + 2 = 4*7 + 2 = 28 + 2 = 30°

How do I find the correct slope on a graph?

-BARSIC- [3]

Answer:

To find the slope of a line from a graph, first choose 2 points along the line and write down the X and Y coordinates for each. Next, find the rise by taking the difference between the 2 Y coordinates. If the line slopes up as it moves to the right, the rise will be positive. If it slopes down, the rise will be negative.
