Question

What is the equation of the line in slope-intercept form?

Answer 1

Answer:

y = 2x

Step-by-step explanation:

( 0 , 0 ) ( 10 , 20)

Slope = Change in y ÷ change in x

         $= \frac{20-0}{10-0}\\\\=\frac{20}{10}\\\\=2$

m= 2; (0,0)

y - y1 =m(x - x1)

y - 0 = 2(x - 0)

    y = 2x

Answer 2

Answer:

y= 2/1x + 0

Step-by-step explanation:

So.. its 20 rise, run 10 or 20/10

Get two points from the graph (10,20) and (20,40)

y2-y1  40-20= 20

x2-x1  20-10 = 10

simplify: 2/1

2/1 is the slope, and zero is the y-intercept
