Question

Please help me!!!!!!

Answer 1

`y=(5)/(8)x+20`

Explanation:

I'll start by finding the slope of this line using the slope formula:

`(70-20)/(80-0)\\(50)/(80)\\(5)/(8)`

Just by looking at the graph I know that the y-intercept is 20, so now I can write the equation in slope-intercept form (y=mx+b):

`y=(5)/(8)x+20`
