Analytic geometry

The slope of the line through (1, 2) and (3, 6) is:

• 1 4
• 2 1/2
• 3 3
• 4 2

The equation of a line with slope 3 and y intercept 2 is:

• 1 y = 3x + 2
• 2 y = 3x - 2
• 3 y = 2x + 3
• 4 y = x + 5

The distance between (1, 1) and (4, 5) is:

• 1 7
• 2 25
• 3 5
• 4 3

Two lines are perpendicular if the product of their slopes is:

• 1 0
• 2 2
• 3 1
• 4 -1

The area of the triangle with vertices (0, 0), (4, 0) and (0, 3) is:

• 1 3.5
• 2 6
• 3 12
• 4 7
