Power-up: Whoever lands on this square will get a ticket that can be used to retry a question if you get it wrong.
Disclaimer: You must use the ticket the second you get a question wrong. If you go the whole game without using the ticket 100 points will be added to your teams total.

The answer is 62.
Write an equation in slope-intercept form.
X: 5, 10, 15, 20
Y: 2, 3, 4, 5
Possible solutions: y=5x+2, y=10x+3, y=15x+4, y=20x+5
Solve the inequality:
2(k - 3) > 6 + 3k - 3
Answer: k < -9
g(x)= 6(x + 2)2 + 5
g(-4) is 29.

What is the vertical line test?
The vertical line test is a way of determining if a line is a function. If you draw a vertical line anywhere on the graph and two points fall on the vertical line, it is not a function and vice versa.
Evaluate.
62 + 3 x 7 -9
The answer is 48.
