Answer:
50
Step-by-step explanation:
1. To solve for the slope, it is vital to use the rise over run formula.
The formula is as follows: y2 - y1 / x2 - x1
Applying the two coordinates in the formula, this would be:
0 - (-50) / 43 - 42
2. Solving the fraction, it is best to simplify the expression on both the numerator and denominator.
0 - (-50) / 43 - 42
0 + 50 / 1
50 / 1
3. The slope of the line is 50.
