Don't report please, technically there's academic questions so

1.) A linear function is two or more points on a graph that create a straight line.

2.) A non-linear function is two or more points on a graph that do not make a straight line.

3.) Area of a Triangle = 1/2 (Base x Height)

4.) Add all of the lengths of the sides together.

5.) pi = circumference/diameter, should give you approximately 3.14 which is pi.

6.) negative / negative = positive
negative / positive = negative
positive / negative = negative

7.) Multiply across and simplify.

8.) Length X Width

9.) You can count integers up and down the number line? That is my best answer for that question.

Hope it helps
