Answer:

y= 20x +30

Step-by-step explanation:

y - intercept of the graph is 30

Slope of the graph is [tex]\frac{20}{1}[/tex]

Answer:

y = 20x + 30

Step-by-step explanation:

y=mx+b

b value = y-intercept, so you find where the line crosses the y-axis.

Find point at (0,30); b = 30

m value = rise/run (rise over run) (y/x)

find the next point that the graph intersects at and count add to it to find 30.

the closest point is at (-1,10)

go back to rise/run

30-10 = 20

0-(-1) = 1

20/1 =20 is your m value

plug m value and b value into equation to form your line.

y=20x+30
