2. Warm ups Convert to Slope-Intercept form: 3x – 2y = 12 x + 3y = 6
Answers:
y = 3/2x – 6
y = -1/3x + 2
y = -2x – 16
y = x + 2
y = -5/2x + 7/2

3. Convert Slope-Intercept to Standard
Objective: To convert a linear Equation from slope-intercept form to standard form.
Standard 6.0

4. Standard Form Ax + By = C Rules: A is positive A,B,C are whole #s
No fractions/decimals

5. Example 1 y = 2x + 4 -2x -2x -2x + y = 4 -1 -1 -1 2x – y = -4
Convert the equation to standard form:
y = 2x + 4
-2x -2x
-2x + y = 4
2x – y = -4
*To make A positive, divide (or multiply) everything by -1

6. TOO y = 4x + 6 y = -3x + 4 Convert the equation to standard form:
Answers:
4x – y = -6
3x + y = 4

7. Example 2 y = -4x + 2 5 +4/5x +4/5x 4x + y = 2 4x + 5y = 10
Convert the equation to standard form:
y = -4x + 2 5
+4/5x +4/5x
4x + y = 2
4x + 5y = 10

*To get rid of the fraction, multiply everything by the denominator.

8. Example 3 m = 3/2 b = 12 Write an equation in standard form:
y = 3x + 12 2
-3/2x -3/2x
-3x + y = 12
-3x + 2y = 24
3x – 2y = -24
Plug into y = mx + b

9. TOO y = 1/2x – 3 y = -1/2x + 5/3 m = 3/2 b = 12
Convert the equation to standard form:
y = 1/2x – 3
y = -1/2x + 5/3
m = 3/2 b = 12
Answers:
x – 2y = 6
3x + 6y = 10
3x – 2y = -24
