Question

Nolan plots the y-intercept of a line at (0, 3) on the y-axis. He uses a slope of 2 to graph another point. He draws a line through the two points. Which equation represents Nolan’s line?

Answer 1

`y=2x+3`

Explanation:

we know that

The equation of the line into slope intercept form is equal to

`y=mx+b`

where

m is the slope

b is the y-intercept

In this problem we have

`m=2\\ b=3`

Remember that the y-intercept is the value of y when the value of x is equal to zero (point 0,3)

substitute the given values

`y=2x+3`
