Question

what is the slope of the line in the xy - plane?

Explanation:

Step1: Select two points on the line

Let's take two points \((3,0)\) and \((4,2)\) from the graph.

Step2: Use the slope - formula

The slope formula is \(m=\frac{y_2 - y_1}{x_2 - x_1}\). Here \(x_1 = 3,y_1=0,x_2 = 4,y_2 = 2\). Then \(m=\frac{2 - 0}{4 - 3}\).

Step3: Calculate the slope

\(m=\frac{2}{1}=2\).
