Question

kevin plotted a linear equation on a graph with 18 as the y intercept. which of the following could be the equation plotted by kevin

Answer 1

The linear equation plotted by Kevin could be anyone who has as an initial value of 18 (value of y when the value of x is equal to zero)

Explanation:

we know that

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

`y=mx+b`

where

m is the slope of the linear equation

b is the y-coordinate of the t-intercept of the linear equation

In this problem we have

`b=18`

substitute

`y=mx+18`

therefore

the linear equation plotted by Kevin could be anyone who has as an initial value of 18 (value of y when the value of x is equal to zero)
