Slope and Points on a Coordinate Plane

A line in the standared (x,y) coordinate plane passes through the points (4,-2) and (-2, 0). The slope of the line is:

• Positive

• Zero

• Negative

• Undefined

• Cannot be determinded from the given information.

IF the slope of a line in the standard (x,y) coordiate plane is 0, and one point on the line is (5,1), which of the following points is also on the line?

• (-2,1)

• (-1,-5)

• (0,0)

• (1,0)

• (5,5)

Based on the trapezoid shown in the standard (x,y) coordinate plance above, what is the slope of the line that is perpendicular to AD and that passed though the point B?

• 0

• 1

• 2

• undefined

In the standard (x,y) coordinate plane, the line passes through (1,-6) and has a slope of 2/3 also passes through (a,2). What is a?

• 7

• 9

• 13

Write the equation of the line with slope 4 through the point (-2, 5).

• y = 4x - 13

• y = 4x + 13

• y = 4x - 3

• y = 4x + 3

Which is an equation for the line that contains (1, 2) and has a slope of 4?

• y = 2x - 4

• y = -2x + 4

• y = 4x - 2

• y = -4x + 2

Write the equation of the line with slope 5/2 through the point (8, -2).

• y = 5/2x + 18

• y = 5/2x - 18

• y = 5/2x + 22

• y = 5/2x - 22

• undefined

• (-2, 8) and (0 , 8)

• 2

• (5 , -10) and (5 , -4)

• 0
