http://www.Media4MathPlus.com In this PowerPoint Presentation we show how to convert a linear equation in Standard Form to a linear function in Slope Intercept Form. We go over the reason for such a conversion and applications that give rise to these equations. We also show how to use our Math Solver for converting Standard Form to Slope Intercept Form.

2. Standard Form
There are times when a linear
equation needs to be expressed in
Standard Form.
Ax + By = C

3. 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?

4. Standard Form
This results in the following
equation:
4x + 2.5y = 750
Sandwich
price
Soda price

5. Standard Form
This is a linear equation in Standard
Form. To graph it, change it to
Slope-Intercept Form.
4x + 2.5y = 750

6. Standard Form
Our Math Solver that converts an
equation from Standard Form to
Slope-Intercept Form shows this
process.

7. Standard Form
Here is the Solver.

8. Standard Form
Input values for A, B, and C. Then
press Solve.

9. Standard Form
Input the specific values. Then
press Solve.

10. Standard Form
Here is the solution.

11. Standard Form
Here is a close-up of the Solution.

12. Standard Form
This is the equation in SlopeIntercept Form. You can graph this
equation on a Graphing Calculator.
y = −1.6x + 300

13. Standard Form
Here is the graph.
Use TRACE
to find
possible
solutions.

14. Standard Form
Test any coordinates along the
graph to verify the equation in
Standard Form.
