IB Math Chapter 3 Review

Write an equation of the line that passes through (3,1) and is parallel to the line y = 3x + 1.

• y = -3x + 1
• y = 3x - 8
• y = -1/3x -8
• y = 3x + 4

What is the equation for the line with a slope of 7 and passes through (0,1)?

• y = -7x + 1
• y = 7x + 1
• y = -1/7x - 1
• y = -1/7x + 1

Given the three equations, decide which answer describes them.
A)   y = 4x + 2
B)   x + 4y = 3
C)   -8y - 2x = 16

• A  is parallel to C
• B is parallel to A
• C is perpendicular to A
• B is perpendicular to C

What is the slope of the line that is perpendicular to the line y = -5x + 3?

• 5
• 1/5
• -1/5
• -5
