Functions: Linear and other Functions Practice MCQ

Question Statement:

Determine the slope of a line that has points (2,3) and (-1,5).

- \frac{2}{3}

- \frac{3}{2}

\frac{3}{2}

\frac{2}{3}

Explanation:

Correct Answer: A

Slope is the change of a line. To find this line one can remember it as rise over run. This rise over run is really the change in the y direction over the change in the x direction.

Therefore the formula for slope is as follows.

$S l o p e = \frac{Δ Y}{Δ X} = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$

Plugging in our given points

(x1,y1)=(−1,5) and (x2,y2)=(2,3),

$S l o p e = \frac{y 2 - y 1}{x 2 - x 1} = \frac{5 - 3}{- 1 - 2} = \frac{2}{- 3} = - \frac{2}{3}$
