M8 1 Qtr TEST 2019

Do the ratios form a proportion?

• Yes, they form a proportion because (8 x 24) = (5 x 15)

• Yes, they form a proportion because they both simplified to equivalent ratio of (1/3)

• No, they do not form a proportion because their cross productive is not equivalent

• No, they don not form a proportion because (8 x 5) is not equivalent to (24 x 15)

• None of the above

Is the graph proportional or non proportional?

• proportional because it is linear and passes through the origin

• proportional because it passes the vertical line test

• non proportional because it doesn't pass through the origin

• non proportional because it doesn't have a constant rate of change

• none of the above

Which graph is proportional?

• B

• C and D

• All of the graphs are proportional

• none of the graphs are proportional

What is the constant of proportionality?

• 1/16

• 1/2

• 2

• none of the above

Is this proportional or not?

• Proportional because it has constant ratio of 1/2 and passes through the origin

• Proportional because it has a constant rate of change and passes through the origin

• Non proportional because it doesn't have a constant rate of change

• Non proportional because it is not linear graph

• None of the above

Is this Linear or non-linear

• Non-linear because it doesn't have a constant rate of change

• Non-Linear because not all the ratios are equivalent
