Work Step by Step
The question defines two variables for the line. The slope (m), and the y-intercept (b): m=0 and b=-2. In order to write the equation for a line containing those requirements, one must use the slope-intercept form: y=mx+b. 1. y=mx+b 2. Plug in known values: y=(0)x+(-2) 3. Simplify: y=-2. Because the slope is zero, this is a horizontal line with a y-intercept at -2.
