Answer:

  • y = 3x

Step-by-step explanation:

Using the given points find the slope and the y- intercept.

  • y = mx + b

The slope is:

  • m = (6 - 3)/(2 - 1) = 3/1 = 3

The y- intercept is:

  • 3 = 3*1 + b
  • 3 = 3 + b
  • b = 0

The line is:

  • y = 3x
  • (1,3)
  • (2,6)

Slope

  • m=6-3/2-1
  • m=3

Equation in point slope form

  • y-3=3(x-1)
  • y-3=3x-3
  • y=3x
