Question

What is the slope of a line that is parallel to the line joining (7,-5) and (-5,7)

Answer 1

Answer:

Step-by-step explanation:

If two lines are parallel then they will have the same slope. So all you need to do is find the slope of the line that joins the two given points. You can use the slope formula $\frac{y_2-y_1}{x_2-x_1}$. You can also graph the two points and use rise over run. $\frac{7-(-5)}{-5-7} =\frac{12}{-12}=-1$
