Additive relationship

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

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

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

Additive relationship is where you add or subtract y and any variable in order to find x.

• True

• False

Answer explanation

Additive relationship is where you add or subtract x and any variable in order to find y

To graph ordered pairs on a coordinate plane, you graph by going up first, then right.

• True

• False

Answer explanation

To graph ordered pairs on a coordinate plane, you graph by going RIGHT first, then UP.

To graph ordered pairs on a coordinate plane, you graph x first, then y.

• True

• False

Answer explanation

Ordered pairs should look like this: (x,y)

• Multiplicative

Additive relationship is where you add or subtract x and any variable in order to find y.

• True

• False
