Supplies for the bake sale cost $30. The parent teacher organization is charging $2 per cookie.

What is the y-intercept for this linear relationship?

• 30

• -30

• 2

• -2

Answer explanation

Be careful! The negative won't always be in the word problem. If they used $30 for costs, then that is debt that they owe. Therefore the 30 should be negative.

What is the y-intercept of the line containing the points (-4, 0) and (1, 5).

• (0, - 4)

• (0, 4)

• (4, 0)

• (-4, 0)

The 4 things we need to identify in order to build a function are:

• f(x)/y:output

  x:input

  m:rate/slope

  b:starting point/y-intercept

• f(x)/y:input

  x:output

  m:starting point/y-intercept

  b:rate/slope

• f(x)/y:output

  x:input

  m:starting point/y-intercept

  b:rate/slope

• f(x)/y:output

  x:rate/slope

  m:input

  b:starting point/y-intercept
