Question

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

Answer 1

-1/2

Explanation:

SLOPE FORMULA:

`\Rightarrow \displaystyle \mathsf{(Y_2-Y_1)/(X_2-X_1)=(RISE)/(RUN)  }}`

Y₂=9

Y₁=7

X₂=(-2)

X₁=(-2)

Solve.

`\displaystyle \mathsf{(9-7)/((-2)-(-2))=(2)/(-4)=(2/2)/(-4/2)={\mathsf{(1)/( -2)=\boxed{\mathsf{-(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
