Question

How do I plot y=2x-4

Answer 1

The formula: y = mx + b
m = slope or rise/run
b = y-intercept

So, the y-intercept would be -4 and the slope would be 2.

First, you would need to find the y-intercept, -4. 

Next, you would use the slope, 2, to find the coordinate. Remember, 2 = 2/1
You would rise 2 and run 1. 

The coordinates to form a line would be (1,-2), (3,2), and (-1,-6). All you would need to do is draw a line through the coordinates. 

I hope this helps!
