Choose the graph with a trend line that best fits the data.
graph 1
graph 2
graph 3
graph 4
Which graph displays the best fitting line?
A
B
C
D
What is the equation of the line of best fit
y= -2x + 10
y= 10x+ 2
y=2x+10
y= 10
What is the equation of the line of best fit?
y= 2x+3
y=3x+2
y= 21x +3
y= −21x +3
Which answer has a correct first step for this system:
3x + 3y = 3
y = 3x + 5
The variable is already isolated, so we've already solved the system.
The variable is already isolated for y, so we substitute it in the first equation and solve for x
3x + 3(3x + 5) = 3

The variable is already isolated for y, so we substitute it in the second equation and solve for x
y = 3(3x + 3y) = 3
3S + 4A = 1740
4S + 3A = 1740
3S + 4A = 530
4S + 3A = 530
5c + 10d = 16.50
5c + 10d = 14.25
5c + 10d = 16.50
5c + 10d = 16.50
