Answer:
The slope is 1/2.
Step-by-step explanation:
Slope formula
[tex]\displaystyle \frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\displaystyle Y_2=4\\\\\displaystyle Y_1=2\\\\\\\displaystyle X_2=5\\\displaystyle X_1=1\\[/tex]
[tex]\displaystyle \frac{4-2}{5-1}=\frac{2}{4}=\frac{2\div2}{4\div2}=\frac{1}{2}[/tex]
The slope is 1/2.
