Algebra-Fall Semester Exam Practice Part 1

Write the equation in point-slope form of the line that passes through the given point and has the given slope:
 (-2, -1); m= -3

• y + 1 = -3(x - 2)
• y + 1 = -3(x + 2)
• y - 1 = 3(x - 1)
• y + 2 = -3(x + 1)

Write the equation of a line parallel to the one pictured through the point (3,1) in point slope form.

• y-1=1/2(x-3)
• y+1=1/2(x+3)
• y-1=-1/2(x-1)
• y+1=-1/2(x+3)

Simplify (-3x⁴y⁵)²

• 9x⁸y¹⁰
• 6x⁸y¹⁰
• 3x⁸y¹⁰
• -9x⁸y¹⁰

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

• y = -4 + 5x
• y = -4 + 5/3x
• y = 4 - 5/3x
• y = 12 + 5x

Leslie cleans the barns for the horses.  Her time spent cleaning can be modeled by the equation y = 15 x + 30, where x represents the number of stalls that contains horses.  What is the meaning of the y-intercept?

• The time it takes to clean one horse
• the time it takes to clean one stall
• the time it takes to clean an empty barn
• the times it takes to clean each of the stalls with a horse
