Question

What is the slope of the line that cuts through the points (1, 2) and (5, 4)?

Answer 1

Answer:

The slope is 1/2.

Step-by-step explanation:

Slope formula

$\displaystyle \frac{y_2-y_1}{x_2-x_1}$

$\displaystyle Y_2=4\\\\\displaystyle Y_1=2\\\\\\\displaystyle X_2=5\\\displaystyle X_1=1$

$\displaystyle \frac{4-2}{5-1}=\frac{2}{4}=\frac{2\div2}{4\div2}=\frac{1}{2}$

The slope is 1/2.
