Respuesta :

Answer:

c)y = 5x

Step-by-step explanation:

The intercept is where the lines crosses the y axis

It crosses at (0,0), so the y intercept is 0

(2,10) (4,20)  are two points on the line

We can find the slope by using

m = (y2-y1)/(x2-x1)

  (20-10)/(4-2)

  10/2

The slope is 5

The slope intercept form of the equation is y = mx +b

y= 5x+0

y= 5x
