• Question 7
120 seconds
Q. How can you tell if a point is a solution to a system?
It makes the first equation true.
The (x,y) coordinates satisfy both equations
It makes logical sense
It makes neither equation negative
• Question 8
120 seconds
Q. What is the
slope-intercept form
of the equation
-8x+2y=4
none
y=2-4x
y=4x+2
y=4x-8y
• Question 9
180 seconds
Q. The talent show committee sold a total of 530 tickets in advance. Student tickets cost \$3 each and the adult tickets cost \$4 each. If the total receipts were \$1740, how many of each type of ticket were sold?
S + A = 530
3S + 4A = 1740
S + A = 530
4S + 3A = 1740
S + A = 1740
3S + 4A = 530
S + A = 1740
4S + 3A = 530
