Question

by observing the vertical and horizontal change of the line between the two points indicated, determine the slope of the line. select the correct choice below and, if necessary, fill in the answer box to complete your choice. a. the slope of the line is (simplify your answer. type an integer or a fraction.) b. the slope is undefined

Explanation:

Step1: Identify two points on the line

Let the two points be $(-2,-2)$ and $(0,2)$.

Step2: Use the slope - formula

The slope formula is $m=\frac{y_2 - y_1}{x_2 - x_1}$. Here, $x_1=-2,y_1 = - 2,x_2=0,y_2 = 2$. Then $m=\frac{2-(-2)}{0-(-2)}=\frac{2 + 2}{0 + 2}=\frac{4}{2}=2$.

Answer:
