Question

what is the slope of the line that has a y - intercept of - 1?

Explanation:

Step1: Select two points on the line

Let's take two points \((0, - 1)\) and \((1,1)\) from the line.

Step2: Use the slope - formula

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