Question

Find the slope of the line that passes through (-2, 7) and (-2, 9)

Answer 1

Answer:

-1/2

Step-by-step explanation:

SLOPE FORMULA:

$\Rightarrow \displaystyle \mathsf{\frac{Y_2-Y_1}{X_2-X_1}=\frac{RISE}{RUN} }}$

Y₂=9

Y₁=7

X₂=(-2)

X₁=(-2)

Solve.

$\displaystyle \mathsf{\frac{9-7}{(-2)-(-2)}=\frac{2}{-4}=\frac{2\div2}{-4\div2}={\mathsf{\frac{1}{ -2}=\boxed{\mathsf{-\frac{1}{2}} }}} }}$

The slope is -1/2.

Answer 2

Y(2)-y(1)/x(2)-x(1)

9-7/-2–(-2)

0

It is a vertical line
