Question

Please help me!!!!!!

Answer 1

Answer:

$y=\frac{5}{8}x+20$

Step-by-step explanation:

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

$\frac{70-20}{80-0}\\\frac{50}{80}\\\frac{5}{8}$

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):

$y=\frac{5}{8}x+20$
