Y varies directly to x. If y = 16 when x = 4, which equation represents this situation?
y=41x
y=12x
y=4x
y=64x
Slopes of parallel lines are...
opposite reciprocals.
opposites.
identical.
always 7.
m = 3
y = -6x + 2
These lines are...
y = 3/2x + 9
These lines are...
y = -5x + 3 through (-5, -4)
Select the statement that best describes the line.
The line is the line of best fit.
The line is a line of best fit because it is increasing and so is the data.
The line is NOT a line of best fit because it does not go through the middle of the data set.
The line is NOT a line of best fit because it does not go through the origin.
Which of the following lines represents the line of best fit for the scatter plot?
A
B
C
D
Find the line of best fit
y = 1.2x + 22
y = 22x + 1.2
y = 12x + 47
y = 47x + 12
Find the line of best fit
y = 0.42x - 20
y = -20x + 0.42
y = 67x + 8.5
y = 8.5x + 67
