Question

Explain in your own words how you would graph the equation y = -4x + 25

Answer 1

See below

Explanation:

First, I would choose three different points with some distance between. Let's do x = -5, x = 0, and x = 5. Next, I would plug those numbers into the equation, like so:

`y = -4(-5) + 25 = 20 + 25 = 45`

`y = -4(0) = 25 = 25`

`y = -4(5) + 25 = -20 = 25 = 5`

Next, I would plot the points [(-5, 45), (0, 25), (5, 5)] on an x-y graph. Finally, I would take a ruler, line it up with the three points, and draw a line through those three points, extending from one side of the graph to the other to show the equation is continuous.
