This is the rate of change if a taxi cab charges $125 rental fee and $0.08 per km.
What is $0.08/ km
This is the equation D = 3t + 7, written in function notation.
What is D(t) = 3t + 7?
This is an example of discrete data.
A Selling dance tickets over 5 days
B Measuring snowfall over 6 hours
What is A selling dance tickets over 5 days?
The point and the slope in this equation: y + 3 = 4(x - 2)
What are (2,-3) and 4?
This is the name of the test you can use to tell whether a graph is a function or not.
What is the vertical line test?
If x = -2, then this is the slope.
What is undefined?
This is the slope when y = 5.
What is 0?
This is the dependent and independent variables from:
"Andrea is selling snow cones for the summer."
What is the number of snow cones (independent variable) and the money earned is the dependent variable.
This is the slope of f(-3)=-8 and f(2)=7
What is 3?
This is the solution for f(x) = 2x + 8 given f(9).
What is 26?
This is the formula to find slope from 2 points.
What is y2-y1/x2-x1 ?
This is the value of "x" in 2x + 5 = 15
What is 5?
This is the strategy you would use to solve the system AND the reason why:
5x + 4y = -14
-3x - 6y = -6
What is elimination?
Because you do not have a coefficient of 1 in front of one of the variables.
This is the strategy for solving this system of equations AND the reason why:
y = 1/3x - 3
4x - 5y = -2
What is substitution?
Because you have the value of y already solved for and can sub it in easily into the second equation.
These are the x- and y- intercepts from 2x - 3y - 6 = 0.
What is (3,0) (x-intercept) and (0,-2) (y-intercept)?
This is the solution for f(x) = 2x + 8 given f(x)=14.
What is 3?
This is the general form of: y - 4 = -2/5 (x - 2)
2x + 5y - 24 = 0
This is the slope from 4x - 6y + 24 = 0.
What is 2/3?
This is the value of the slope and its meaning in this situation:
If I catch 7 caribou my profit is $1550.
When I only caught 3 caribou I was in debt $2050.
Slope is the amount of money each caribou is worth. In this case, $900.
This is the equation in slope-intercept form for this situation:
If I catch 7 caribou, my profit is $1550.
If I catch 3 caribou I am in debt $2050.
What is y = 900x - 4750?
This is the x- and y- intercepts from the equation 3x - 9y + 18 = 0
What is (-6,0) x-intercept and (0,2) y-intercept
This is a perpendicular slope to 4x - 6y + 24 = 0
What is -3/2?
This is how you would prove algebraically that triangle ABC is a right triangle or not.
A(1,1)
B(3,8)
C(6,7)
What is: find the slope of the three lines AB, AC, and BC using the slope formula y2-y1/x2-x1. If two of the lines have negative reciprocals for their slopes, then they have perpendicular slopes which means they form a right angle and therefore triangle ABC would be a right triangle.
This (-2,1) is the solution set for one of these two systems:
A x + y = -1
3x - 2y = -7
B x + y = -1
2x - 3y = -7
What is B?
This is the value of the y-intercept given m = 3/5 and (5,1).
What is -2?
