Question

7 find the slope of the following line. a $\frac{1}{2}$ b $- 2$ c 2 d $-\frac{1}{2}$

Explanation:

Step1: Select two points on the line

Let's take two clear - cut points on the line, say (0, 1) and (1, 3).

Step2: Use the slope formula

The slope formula is $m=\frac{y_2 - y_1}{x_2 - x_1}$. Here, $x_1 = 0,y_1 = 1,x_2=1,y_2 = 3$. Then $m=\frac{3 - 1}{1 - 0}=\frac{2}{1}=2$.
