5. Example 1 6 -4 Write the slope-intercept form of the equation.
Writing slope-intercept form equation given
SLOPE & Y-INTERCEPT
Write the slope-intercept form of the equation.
Slope = Y-intercept = -4 6 -4
y = _____x + ________
y = 6x - 4

6. Writing equations from Standard Form to
Example 2
Writing equations from Standard Form to
Slope-intercept Form
3x + 3y = 12
-3x x
3y = x
y = 4 - x 3 3 3
y = -x + 4

7. Writing slope-intercept form equation given
Example 3
Writing slope-intercept form equation given
SLOPE & 1 point
Through: (3, 1), Slope = 2 x y
1 = 6 + b
y = 2x + b
1 = 2(3) + b 2 -5
b = -5
y = _____x + ______
y = 2x - 5

8. Example 4 m = 1 Through: (0, -5) and (1, -4)
Writing slope-intercept form equation given
2 points
Through: (0, -5) and (1, -4)
Step 1: Find the slope using the formula
m = 1

9. Step 2: Find the value of b
Through: (0, -5) and (1, -4)
y = 1x + b
-5 = 1(0) + b
-5 = b 1 -5
b = -5
y = _____x + ______
y = 1x - 5
