Answer:  y = 3x + 1

<u>Step-by-step explanation:</u>

The equation is in Slope-Intercept format: y = mx + b      where

  • m is the slope <em>(difference in y's over difference in x's)</em>
  • b is the y-intercept   <em>(value of y when x = 0)</em>

m=\dfrac{y_2-y_1}{x_2-x_1}\\\\\\\text{Let }(x_1,y_1)=(0,1)\quad \text{and}\quad \text{let }(x_2, y_2)=(1,4)\quad then\\\\m=\dfrac{4-1}{1-0}=\dfrac{3}{1}=3

b = 1     <em>refer to the table that shows y = 1 when x = 0</em>

Now input m = 3 and b = 1 into the Slope-Intercept formula:

y = 3x + 1
