1. Slope-Intercept
and
Standard Form
of a Linear Equation

2. y = mx + b
Write an equation for each graph in slope-intercept form.
y = 5/3x - 3
y = - 3/5x + 2

3. What is the y-intercept?
y = mx + b
Write an equation for each graph in slope-intercept form.
Where does the line
cross the y-axis?
y-axis
What is the y-intercept? -3
b = -3

y = 5/3x - 3

5. y = mx + b
Write an equation for each graph in slope-intercept form.
y = 3
x = - 4

6. y = 5/3x - 3 y = - 3/5x + 2 5x - 3y = 9 3x + 5y = 10 Ax + By = C
Change each of the following equations into Standard Form.
y = 5/3x - 3
y = - 3/5x + 2
5x - 3y = 9
3x + 5y = 10

7. Ax + By = C
Change each of the equations into standard form.

8. y = 5/3x - 3 -5/3x -5/3x - 5/3x+ y = -3 (-3)(-5/3x+ y) = (- 3)(-3)
Ax + By = C
Changing the equations into standard form.
y = 5/3x - 3
-5/3x /3x
- 5/3x+ y = -3
(-3)(-5/3x+ y) = (- 3)(-3)
15/3x - 3y = 9
5x - 3y = 9
