STAAR Review 1

Write in slope intercept form
5x - 3y = -9

• y = (5/3)x - 3
• y = (5/3)x + 9
• y = (5/3)x + 3
• y = (3/5)x + 3

Write the equation in slope-intercept form:
5x - 3y = 12

• y = 5x - 4

• y = 5/3x - 4

• y = -5/3x + 4

• y = 5x + 12

Change this standard form to slope form.

3x + 2y = 8

• y = 3x +4

• y = - 3/2x + 4

• y = 2x + 4
