Question

Find the slope passing through the points (5,9) and (5,-2)

Answers:
A. -11
B. 0
C. 11
D. Undefined

Answer 1

The slope can be found with this equation:
\[m=\frac{y_2-y_1}{x_2-x_1}\]
So for your coordinates, plug in the values and evaluate to find m, which is the slope.

Answer 2

Because both the "x" values are the same, this is a vertical line. In a vertical line, the slope is undefined.

Answer 3

I agree. @sistagurl21: Would you please actually sketch the locations of these two given points on the xy plane, and then draw a line through them both? Describe what you see.

Answer 4

Thanks you guys but I cannot graph it ! I found the answer !
