Question

How do you graph `y=2x-2`?

Answer 1

graph{2x-2 [-10, 10, -5, 5]}

Explanation:

In your equation `(y=2x-2)`, `-2` is your y-intercept and `2` is your slope.

Start by plotting your y-intercept on your y-axis (`0, -2`).

Then, from the dot you just plotted, you can begin plotting your slope. Since your slope is `2/1` (or just two), and given that slope is rise/run, you can plot this by going to the right once, and up twice. Repeat this pattern, and extend your line.

Your graph should look similar to the graph above.
