- The amount of 1 shirt before the shipping fee is $16
- If the shipping fee was increased, b changes
- If the cost per shirt was increased, m changes
<h3>What is linear equation?</h3>
A linear equation is an equation of a straight line, written in one variable. The only power of the variable is 1. Linear equations in one variable may take the form a x + b = 0
As it is given that the equation is y =mx + b
We have two coordinates as; (2,33) and (3,48)
So, we get
2m + b =33..............................(1)
3m +b = 48...............................(2)
On Solving equation (1) and(2) we get,
m= 16
As the shipping fee was increased then b changes
and if the cost per shirt was increased then m changes
The amount of 1 shirt before the shipping fee is $16
If the shipping fee was increased, b changes.
If the cost per shirt was increased, m changes.
