Question

find the slope of the line in this graph.
o $\frac{1}{2}$
o 2
o -2
o $-\frac{1}{2}$

Explanation:

Step1: Select two points

Let's take two points on the line: $(0,0)$ and $(2, - 1)$.

Step2: Apply slope - formula

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

Answer:

$-\frac{1}{2}$
