Step-by-step explanation:
Slope formula:
[tex] \frac{y2}{x2} - \frac{y1}{x1} = m[/tex]
m = slope
Substitute the points into the formula format:
[tex] \frac{ - 14}{ - 15} - \frac{ - 2}{ - 7} = m[/tex]
Using the negative rule for subtraction:
[tex] \frac{ - 14}{ - 15} + \frac{2}{7} = m[/tex]
Solve:
[tex] \frac{ - 12}{ - 8} = m[/tex]
Simplify:
[tex]1\frac{1}{2} =m[/tex]
The slope equals 1 1/2.
