9/13 quiz

Write an equation in standard form for the line that is parallel to the graph of

–8x = 5 – 4y and has y-intercept –0.5.

• x – 0.5y = 0.25

• 10x – 5y = 2.5

• 4x – 2y = 1

• 2x – y = 1

 Find the slope of the line that passes through (-4.5 , 3.5)and (3, 3.5).

• -6

• undefined

• 0

The graphs of which pair of lines are perpendicular?

• 2x – 3y = 12,

  y = – x + 5

• y = 4x + 13,

  y = x – 13

• 3x + 2y = 6,

  2x – 3y = 7

• x + y = 1,

  2y = –2x + 2

Write an equation in slope-intercept form for the line that has a slope of –4 and passes through (1, 2).

• y = –2x + 4

• y = –4x + 6

• y = –4x + 2

• y = –4x + 9

Write an equation in slope intercept-form for the line that passes through (0, 5) and is parallel to the line whose equation is 4x – y = 3.

• y = 4x – 3

• y = 4x + 5

Write an equation in slope-intercept form for the line that passes

through (–1, 2) and (1 , 8)

• y = 3x – 1

• y = 3x – 5

• y = 5x + 3

• y = 3x + 5

What is the slope of a line that is parallel to the graph of 2x – 3y = 6?
