4/9 Math 1 Warm-up

A line is parallel to   y = 2x - 7.
What is it's slope?

• -2
• 1/2
• -1/2
• 2

 Which equation is parallel to: $y=\frac{5}{7}x+2$ 

•  $y=-\frac{7}{5}x+1$  
  

•  $y=\frac{7}{5}x+4$  
  

•  $y=-\frac{5}{7}x-3$  
  

•  $y=\frac{5}{7}x+5$  
  

Which pair of equations below produce graphs of parallel lines?

• y = 2x + 1

  y = -1/2x + 1

• y = 2x + 3

  y = -2x + 3

• y = 2x - 1

  y = 1/2x - 1

• y = -x + 4

  y = -x + 2

Which of the following lines is PARALLEL to the graph of y = -6x + 3 and goes through the point (-1,4)?

• y=1/6x +25/6

• y = 1/6x + 4

• y = -6x - 2

• y = -6x + 4

Solve for y:

x + y = 4

• y = x + 4

• y = -x + 4

• y = $\frac{4}{x}$

• x = y - 4
