What is a linear function?
A linear function is a line that has a constant slope meaning that on a graph it is a straight line.
100
Which table is a linear function?
C
100
What is the equation of this line in y=mx+b form?
y=-4x+2
100
What is the slope of the line that passes though the points (0,2) and (1,3). Make sure to reduce it if able.
The Slope is 1
100
y=2x+1
Is this a linear function?
True
200
What does the m in the equation y=mx+b mean?
m is our slope
200
Which table is a linear function?
Table 2
200
What is our slope for this line?
1/2
200
What is the y-intercept of the line that passes though the points (-1,2) and (1,6)
(0,4)
because (-1,2) and (1,6) gives me a slope of 4/2 = 2
200
y = 7x+ 10
This is NOT a linear function
false
300
What does the b in the equation y=mx+b mean?
b is our y-intercept.
300
This is a Linear equations. if we added a 600 to the minutes included, x what would the cost of plan ($),y be?
44
300
What is the equation of the line that passes though the points (0,2) and (1,3). Make sure to reduce it if able.
y=x+2
300
Which equation represents a linear function?
y = 3x2+1
y = 3x+10
x= 3
y = 3x+10
300
This is a linear function!!!
False
400
Would this table with these output be a linear function?
No because the output is not constant.
400
D
400
What is the equation of this line in y=mx+b form?
y= -1x +0 or y= -1x
400
Which equation does NOT represents a linear function?
y=3x+1
y=x2+10
y= 10 + 2x
y=x2+10
400
y= 15
Is this a linear Function?
True
500
Would the equation
y = 112.421
be a linear function?
yes because a slope of 0 is still a constant slope
500
C
500
What is the equation of this table in y=mx+b form
y=-0.5x+2
500
What is the slope that passes though the points (-11,5) and (25,11). Make sure you reduce it if able.
6/36 = 1/6
500
This is a linear Function.
False.
