Question

Consider a line passing through the points (0,0) and (2,2). Then the slope of this line is _____.

• A. 2
• B. 1
• C. 1/2
• D. 0

Answer 1

The correct option is B

1

Given two points $(x_1,y_1)$ and $(x_2,y_2)$, the slope of the line joining the two points is given by $\frac{y_2-y_1}{x_2-x_1}$.
Here,
$x_1=0,x_2=2,y_1=0and{y}_2=2$
Slope = $\frac{2-0}{2-0}$ = $\frac{2}{2}$ = 1
