y = mx + b

100

How many solutions does a pair of parallel lines have?

No solutions.

100

What is the difference between radius and diameter?

200

Can a negatie slope be proportional?

Yes

200

No.

200

Graph the equation y = 15x + 5. I will come check your paper for the correct answer.

Varies.

200

If you see one line on a graph, and the question reads "how many solutions does the system of equations have?".... What does that mean?

It means there are infinitely many solutions, they are the same line. 

200

What is the formula for circumference of a circle?

y = pi * diameter

300

How do you know if a graph is proportional?

It has to be a straight line starting at the origin (0,0)

300

How do you find domain and range of a function on a table?

Domain is the list of x-values from least to greatest, range is the y-values from least to greatest.

300

If I am creating a graph with time as my x-axis and distance as my y-axis, would my graph be increasing or decreasing as I walk away from my house?

Increasing.

300

Which ordered pair is the solution to the system of equations?

y = 2x-4

y = -2x+4


(2,0)

37

400
If a graph has a y-intercept other than 0, is it proportional?

No.

400

Is your domain your independent or dependent variable?

Independent

400

What is the formula for finding slope on a graph? On a table?

rise over run, y2-y1/x2-x1

400

What would a non proportional graph look like?
Example answers: Curved line, not starting at zero
500

Draw a function graph of the following scenario: I am on my way to school and I sit in my driveway for 10 minutes to let my car warm up, I start driving towards the school and stop to get starbucks, I forgot my wallet at home and have to go all the way back. I leave again and go straight to the school this time. 

Varies

500

What is the difference between linear and proportional?

Linear is a straight line, proportional is a straight line starting at zero.

500

Graphs with infinitely many solutions have the same what?

Slope and y-intercept
