What is the contrapositive of the conditional statement? if two variables are directly proportional, then their graph is a linear function. if two variables are directly proportional, then their graph is not a linear function. if two variables are not directly proportional, then their graph is not a linear function. if the graph of two variables is a linear function, then the two variables are directly proportional. if the graph of two variables is not a linear function, then the two variables are not directly proportional.

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !

22.83 repeating

step-by-step explanation:

137 ÷ 6 is 22.8333333 therefore we understand that 3 is repeating.

happy to

pls mark as brainliest

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides

step-by-step explanation:

- (2, -7)

- lines r and s and lines t and u must be parallel
