Practice Problems
Try them, get help one step at a time, then print how it went.
Practice: try it, then get help one step at a time
Predicting from m and b, reading a strange ending, and building systems with a chosen number of solutions. Hint gives a nudge, Show next step shows one worked step at a time, Reveal answer checks, and Hide help / start over clears the card.
My results
Finished the practice? Print a page that shows each question, what you typed or chose, the correct answer, and how it went. Good for showing a teacher or keeping in a folder.
Exit ticket
On paper or an index card. Use the math word and the plain-English word.
- How many solutions does y = 4x + 1 and y = 4x − 3 have, and why?
- What does it mean when solving ends in 0 = 0?
- Predict for y = −2x + 5 and y = 3x − 5.
- Write an equation that makes a system with y = x + 2 have no solution.

- None: same slope, different y-intercept, parallel.
- Infinitely many solutions: the two equations are the same line.
- Different slopes: one solution (it is (2, 1)).
- Any y = x + b with b not 2, for example y = x − 4.
