The line passing through the points $(2, 5)$ and $(6, 13)$ has what slope?
A$\dfrac{1}{2}$
B$2$
C$4$
D$8$
Answer & Solution
Correct answer: B. $2$
Slope $= \dfrac{y_{2} - y_{1}}{x_{2} - x_{1}} = \dfrac{13 - 5}{6 - 2} = \dfrac{8}{4} = 2$.
- Trap C ($4 = 8 / 2$) reverses rise and run or divides incorrectly.
- Trap D returns the rise alone.
- Trap A inverts the slope.
