Table Linear Functions

Jenny writes the equation y = 1/2x +5.
Why is she incorrect?

• The slope is -2, the equation should be
  y = -2x + 5

• The y-intercept is 4, the equation should be y = -2x + 4

• The slope is -1/2, the equation should be
   y = -1/2x + 5

• The y-intercept is -5, the equation should be y = -2x - 5

Write the equation with a slope of -3 and a y-intercept of (0, 4).

• y = -3x + 4

• y = -12x

• y = x + 4

• y = 4x - 3

A camp charges families a fee of $625 per month for one child and a certain amount more per month for each additional child. Use the graph to write an equation in slope-intercept form to represent the amount a family with x additional children would pay.

• y = 625x + 225

• y = 225x 

• y = 225x + 625

• y =  625

Creating tables from linear functions: Create a table for the linear function y = 2x - 1 for x values 0, 1, 2, 3, and 4.

• (0, 0), (1, 2), (2, 4), (3, 6), (4, 8)

• (0, -2), (1, 0), (2, 2), (3, 4), (4, 6)

• The table for the linear function y = 2x - 1 with x values 0, 1, 2, 3, and 4 is: (0, -1), (1, 1), (2, 3), (3, 5), (4, 7)

• (0, 1), (1, 3), (2, 5), (3, 7), (4, 9)
