Standard Form
There are times when a linear equation needs to be expressed in Standard Form.
Standard Form
Let’s look at an example:•A deli sells sandwiches for $4 and sodas for $2.50. In one day it earned $750. What combination of sandwiches and sodas could it have sold?
Standard Form
This results in the following equation:
Sandwich price Soda price
Standard Form
This is a linear equation in Standard Form. To graph it, change it to Slope-Intercept Form.
Standard Form
Our Math Solver that converts an equation from Standard Form to Slope-Intercept Form shows this process.
