Question

How do you graph the function `y=-2x-3`?

Answer 1

See solution below.

Explanation:

It's important to plot a couple of points first. That is, select reasonable `x` values for inputs and calculate the corresponding `y` values. Putting them in a table like this makes it easier to draw the graph.

Next, plug these points `x`-values (moving left or right along the horizontal axis) and `y`-values (moving up or down along the vertical axis). Here is what you get.

Finally, connect the dots to see the graph.
