Question

How do I graph y = -1 = 2x and y = -4 + 2x?

Answer 1

Basically this is how it should look like when you follow the steps from the person who explained :]

Answer 2

Slope = Rise/Run

To graph, you first need the y-intercept.

In y = -1 + 2x, the y-intercept is -1. Start in -1 and then go two units up, and 1 unit to the right which will represent the slops, 2.

In y = -4 + 2x, the y-intercept is -4, so you'll start at -4, then go 2 u its up, and 1 to the right which will represent the slope, 2.

To find y-intercept:

y = mx + b | main things: m = slope b = y-intercept

Hope it helps!
