Question

If A(7,5) , B(4,3) and C(-2,-3) are the vertices of a triangle, Find the slope of side AB.

• A. $\frac{1}{3}$
• B. -1
• C. $\frac{2}{3}$
• D. 1

Answer 1

The correct option is C $\frac{2}{3}$

Given A(7,5) , B(4,3) and C(-2,-3)

For side AB ,
$x_1=7,x_2=4,y_1=5,y_2=3$
Slope of Side AB = $\frac{y_2-y_1}{x_2-x_1}=\frac{3-5}{4-7}=\frac{2}{3}$
