Y= 2x-4 is the slop-intercept form your'e looking for there isn't a lot of work include because you; re just plugging what you have in the equation y=bx+m

y = mx+b  where m is the slope and b is the y intercept

y = 2x-4  

the slope is 2

the y intercept is -4

Explanation:

Slope-intercept form: →

m: represents the slope and is constant.

b: represents the y-intercept.

The y-intercept is the point on a graph at which the graph crosses the y-axis.

You had to used rise/run.

But the slope is 2

But the y-intercept is -4.

Hope this helps!

Thanks!
