Answer:

y = 12x +0 or just y = 12x

Explanation:

We can take two lines off that line such as (5,60) and (10,120) and then use the slope formula.

y2 - y1 / x2 - x1

120 - 60 / 10 - 5

60 / 5 or 12 / 1

That shows us that our slope is 12/1 or 12.

y = mx + b is what we want. The m represents slope. The b represents the y intercept or where the line crosses across the y axis. We can clearly see the line crosses the y axis at 0, so our y intercept is 0.

Fill in the formula to get:

y = 12x +0
