What is the slope of this line?

Mamont248 [21]

Answer:

y= 2x

Step-by-step explanation:

The slope is 2

The y-intercept is zero because it intersects the origin so you do not need to right that.

Now just put it is slope-intercept form.

Hope you remember me because I just answered your other question 2 minutes ago! LOL :D
