Jerry has a new job and earns a salary of $45,000. Victoria has a new job and earns a salary of $54,000. Jerry will receive a salary increase of $2,500 per year, and Victoria will receive a salary increase of $1,500 per year. Write an equation that can be used to find x, the number of years it will take Jerry to earn the same salary as Victoria?

A relation contains the points (1, 2), (2, −1), (3, 0), (4, 1), and (5, −1). Which statement accurately describes this relation?

• The relation does not represent y as a function of x, because each value of x is associated with a single value of y.

• The relation represents y as a function of x, because one value of y is associated with two values of x.

• The relation does not represent y as a function of x, because each value of y is associated with two values of x.

• The relation represents y as a function of x, because each value of x is associated with a single value of y.

The coordinates of the vertices of a rectangle are A (5, 3), B (5, − 9), C ( − 1, − 9), and D ( − 1, 3).

Which measurement is closest to the distance between point B and point D in units?

Ignore the questions above instead identify the steps to solve this problem.

• 1. make a table

  2. Choose two points

  3. y1~mx1+b

• 
• 
• y=mx+b

The total surface area of a cylinder with a radius of 1 unit and height of x units can be represented by

y = 2πx + 2π

The equation above is called non proportional because:

• the y intercept is not equal to zero and the equation represents, y=mx

• the y intercept is not equal to zero and the equation represents, y=mx+b

• the y intercept is equal to zero and the equation represents, y=mx+b

• the y intercept is equal to zero and the equation represents, y=mx-b
