Linear Equation Forms and Graphs

Bob has $150 in his savings account and saves $40 per month.

• 150 + 40

• 40x + 150

• 150x + 40

In the equation y = 14x, what is the constant of proportionality?

• y

• x

• 14

Write an equation for this situation.

• y=9.75x

• y=19x

• y=19.25x

• y=9.5x

What makes a graph proportional?

• Linear

• The line is only in quadrant 1

• Curvy line

• Linear and the line goes through the origin

Which graph is proportional?

• A

• B

• C and D

• All of the graphs are proportional

Does the table represent a proportional relationship?

• Yes.

• No.

Does the equation x - 5 = y form a proportion?

• Yes, because k = -5

• Yes, because it forms a line

• No, because the lines does not pass through the origin.

• No, because the line passes through the origin.
