Graphing Additive Relationships

Which of the equations below matches the values in the table?

Which representation best describes the relationship between all the values of x and y shown in the table?

• y is 50 times x

• x = 50 + y

• Jemaine started by doing fifty push-ups and then increased the number of push-ups by one each day.

• 

Apples weighing 30 pounds are placed in a crate that weighs p pounds. Which equation can be used to find t, the total weight of both the crate and the apples in pounds?

• t = 30p

• t = p + 30

• p = t + 30

• t = 30 - p

Which equation describes the following relationship between x and y?

y is 8 less than x.

• y = 8x

• y = 8 - x

• y = 8 + x

• y = x - 8

What type of relationship is represented in this equation:

x + 3 = y

• Additive and the graph would NOT cross through the origin

• Multiplicative and the graph would cross through the origin

What is the correct equation for an additive relationship?

• y = x+a
• x = y+a
• y = ax
• a/x = m
