Algebra Final Review #2

Which line is parallel to y = 5x - 10 ?

• y = -1/5 x - 3

• 5x + 2y = 8

• 10x - 2y = 4

• y = -5x + 1

Choose the line that is perpendicular to y = 6x - 7.

• 18x + 3y = 9

• 3x + 18y = -18

• y = 1/6x + 2

• y = -6x + 3

Find the slope of the line if the points (-4, 5) and (1, 20) are on the line.

• 5

• -5

• 3

• -3

Write the equation of the line that has a y-intercept of 5 and a slope of 2.

• y = -5x + 2

• y = 2x + 5

• y = 5x + 2

• y = 2x - 5

Find the equation of the line that has a slope of -3/2 and passes through the point (8, -5)

• y = -3/2 x + 1

• y = -3/2 x - 17

• y = -3/2 x + 7

• none of these

 x – 6 < 15 + 8x

•  x < –3

•  x > –3

•  x > 3

• x < 3

28 - x > 7(x - 4)

• x < 0

• x < 7

• x > 0

• x > 7

• x < 5

• x > 5

• x < 7

• x > 7

-50 < 7x + 6 < -8

• x < –8 or x > –2

•   –8 < x < –2

• All real numbers

• No solution

Figure out where these lines intersect:

y = 4x - 9

y = x - 3

• (1, -2)

• (2, 1)

• (1, 2)

• (2, -1)
