Expert Solution
Step 1

Given equation: y=-2x-1 , which is a linear equation of form y=mx+c (Slope -intercept form).

i.e. The given equation is representing a line.

Step 2

A linear equation gives the location of a line.

To plot it on a cartesian plane, we can plug any random value (at least 2 different values) of x or y and evaluate the value for the corresponding variable.
