Slope and Y-intercept
In the general slope-intercept form, y = mx + b, this represents the slope.
What is "m"?
This is the formula for linear equations when graphing.
What is y = mx + b?
Tantastic charges a reservation fee of $20 and $1 per minute in a tanning bed.
BetterSun charges no reservation fee but charges $2 per minute in a tanning bed.
This is the "b" value for Tantastic.
What is $20?
The number of solutions for parallel lines.
What is 0 or no solutions?
This symbol is associated with "less than".
What is < ?
In the slope-intercept form, y = mx + b, this represents the y-intercept.
What is "b"?
The coordinates for the y-intercept on any coordinate graph.
What is (0, b) or (0, # of y-intercept?
Tantastic charges a reservation fee of $20 and $1 per minute in a tanning bed.
BetterSun charges no reservation fee but charges $2 per minute in a tanning bed.
This is the "b" value for BetterSun.
What is $0 or "blank"?
The number of solutions for intersecting lines.
What is one?
These two symbols create inequalities that form a dashed line.
What are < and > ?
This term is defined as the rate of change of the equation. In a word problem, it defines the rate of change with words like "per, for each, for every..."
What is slope?
From a TABLE of data points, this is how do you find the y-intercept.
What is "look for the x = 0 value" and then find its associated "y value"?
Tantastic charges a reservation fee of $20 and $1 per minute in a tanning bed.
BetterSun charges no reservation fee but charges $2 per minute in a tanning bed.
This is the "m" value for Tantastic.
What is $1 per hour?
The third type of system which has an INFINITE number of solutions.
What is coinciding?
This "term" describes the area where the solution to a system of inequalities is found.
Where is the region of overlapping?
This term is defined as the beginning of the data. In a word problem, this term is identified as a "one-time charge or initial fee."
What is the y-intercept?
From a table of data points, this is how you find the slope?
What is calculate the change in y's over the change in x's?
Tantastic charges a reservation fee of $20 and $1 per minute in a tanning bed.
BetterSun charges no reservation fee but charges $2 per minute in a tanning bed.
This is the "b" value for BetterSun.
What is $2 per hour?
The solution to this system:
y = -3x + 4
y = 10 - 3x
What is no solution?
If you graph the inequality
y < 3x -4 the direction of the region is where.
What is "you would shade DOWN on the y-axis" or "you would shade BELOW the graph using the y-axis?
If you are given the equation, y = 10 + 5x, these are the values of the slope and the y-intercept.
What is the slope = 5 and b = 10?
If m = -2 and b = 10, this is the linear equation representing this line.
What is y = -2x + 10?
Tantastic charges a reservation fee of $20 and $1 per minute in a tanning bed.
BetterSun charges no reservation fee but charges $2 per minute in a tanning bed.
This is the full linear equation for Tantastic.
What is y = 1x + 20?
The solution to this system:
y = -2x + 4
2y = -4x +8
What is an infinite number of solutions?
Graph the system of inequalities,
y > 2x + 4
y < - 3x - 5
The status of the point (-6,2). (solution or not a solution)
What is a solution?
