Begin with have A, B, and C values equal to one. Manipulate the A value by increasing and decreasing it (Remember negative numbers). What do you observe happening when the A value is increased? Decreased? 1. Reset the A value back to 1. Manipulate the B value by increasing and decreasing it. What do you observe happening when the B value is increased? Decreased? 2. Set the A and B values to be equivalent. Do this with multiple numbers. What do your observe? 3. Set the A and B values to be opposites. Do this with multiple numbers. What do your observe? 4. Reset the A and B values back to 1. Manipulate the C value by increasing and decreasing it. What do you observe happening when the B value is increased? Decreased? 5. Manipulate the A and C values at the same time. What do you observe? Do your previous observations for each value still occur? 6. Manipulate the B and C values at the same time. What do you observe? Do your previous observations for each value still occur? 7. Think about what information equations in Slope-Intercept Form provide you. What information do equations in Standard Form provide? How is Standard Form helpful?
