Linear Equations

Which equation best represents the relationship between x and y in the table shown?

• y= 5x+5
• y=1/5x+5
• y=15x+5
• y=10x+5

Write the equation in slope intercept form

• y = 2x + 3
• y = 3x + 2
• y = 2x - 1
• y = idk

What is the slope a horizontal line?

• -1
• undefined
• 1
• 0

Write the following equation in slope-intercept form:
4x - 3y = 12

• y = -4/3x + 3
• y = -4x + 12
• y = 4/3x - 4
• y = 4/3x - 12

If you convert the equation

y-4=3(x+3)

into slope-intercept form, what is result?

• y=23x-1/23

• y=3x+13

• Mr. Tabrys

• y=13-3x

Give the slope and y-intercept
6x - 3y = -9

• slope is 6 
  y-intercept is 9
• m=2
  b=3
• slope is 2
  y-intercept is -3
• m = 3
  b = 2

Paul the plumber charges $25 for a service call.  He then charges $100 an hour.  Write a linear equation to model this situation.

• y = 100x
• y = 25x
• y = 25x + 100
• y = 100x + 25
