I add five to nine and get two. The answer is correct, but how?

When it is 9 p.m., add 5 hours to it and you will get 2 p.m.

300

What is the equation of this graph?

y=x2

400

How do you find the slope of a linear graph? (You have to say the name of the rule and explain the process)

Rise-over-run: Pick two points on a graph. Rise (up or down) from one point and then run (left or right) to the other point. 

400

Find the answer by interpreting the statement: If f(x)=76x−17 and x=3

f(3) = 211

400

What is the equation of this line?

 y = -2x+1

400

You are given 3 positive numbers. You can add these numbers and multiply them together. The result you get will be the same. Which are the numbers?

1, 2, and 3

400

Solve for x:

x1 = 2

x2 = 7

500

How do you find the equation of a linear graph?

Find the slope using rise-over-run. Find the y-intercept by finding a point where the line crosses the y-axis. Then put both numbers in y=mx+b format. 

500

Find the answer by interpreting the statement: f(x) = 9x2+10 when x = 7

f(3) = 451

500

What is the equation of this line?

y=-(2)/(3)x+5

500
