Question

Find the slope of the line passing through the following pairs:

(-1, 3) and (3, 5)

• A. $\frac{1}{4}$
• B. $2$
• C. $\frac{1}{2}$
• D. $-\frac{1}{2}$

Answer 1

The correct option is C $\frac{1}{2}$

Slope of the line passing through points $(x_1,y_1)$ and $(x_2,y_2)$ $=$ $\frac{y_2-y_1}{x_2-x_1}$
Hence, slope of the line passing through $(-1,3)$ and $(3,5)=\frac{5-3}{3-(-1)}=\frac{2}{4}=\frac{1}{2}$
