Chapter 3 - Section 3.1 - Graphing Equations - Exercise Set: 87b


y=14 inches

Work Step by Step

We are given that the equation is $y=2x+6$, where y is the perimeter of a rectangle whose width is a constant 3 inches and whose length is x inches. We can plug in $x=4$ into the equation to calculate the perimeter. $y=2\times4+6=8+6=14$ inches This y-coordinate corresponds to x=4 on the graph of the equation.
