How can you identify linear vs. nonlinear in a Graph? Table? Equation?
Graph - it's a straight line
Table - Constant rate of change
Equation - Can be written in y=mx + b format
100
What is the "Slope-Intercept" formula?
What is y = mx + b
100
Horizontal lines have a slope equal to this?
What is ZERO
100
Solve for p.
p/5 =6
What is 30
100
True or false.
Slope refers to the steepness of a line?
TRUE
200
Is the function y = 3x + 4 linear or nonlinear?
Linear
200
What is the slope and y-intercept of the line y = 3x + 2
slope = 3
y-intercept = 2
200
The formula for finding slope between any two points.
What is:
m = (y2-y1)/(x2-x1)
200
Solve for d.
2 = d - 6
What is 8
200
True or False.
Linear equations are always straight lines.
TRUE
300
Is the function y = 1/2x -12 linear or nonlinear?
linear
300
What is the slope and y-intercept of the line:
y=-1/4x - 6
Slope = -1/4
y-intercept = -6
300
The slope of the line that passes through (2,2) and (1,1).
What is "m" = 1
300
Solve for s.
8 = 2s
What is 4
300
How do we find slope on a graph?
What is Rise(or Fall) over Run
400
Is the function y = 2/x + 4 linear or nonlinear?
Nonlinear.
Remember, it has to be in y=mx +b, where m is multiplied by x. In this equation, x is NOT being multiplied, but rather divided.
400
What is the slope and y-intercept of the following equation:
y=-x + 3
Slope = -1
y-intercept = 3
400
The slope of the line that passes through (-3,2) and (-5,-1).
What is 3/2
400
Solve for r.
9 - 2r = 3
What is 3
400
What is the Greek symbol for "change"
What is "delta" OR What is a triangle.
500
Is the function y = 2^x linear or nonlinear?
What is nonlinear
500
What is the slope and y-intercept of the following equation:
y=5
Slope = 0 (zero) - there is no slope.
Since there is no x, there is no slope. Remember: zero times x would be 0 and therefore there would be no x.
y-intercept = 5.
500
The slope of the line that passes through (2,4) and (2,-3).
What is "UNDEFINED!" because this is a vertical line and "unsolvable"
500
Solve for r.
8 - 2r = 4
What is 2.
500
Put the following equation into y=mx + b format:
2y = 4x + 8
