Solve problems by interpreting graphs of linear and non-linear relations, including problems involving direct and partial variation
10 tutor-authored questions for this Ontario curriculum expectation, ordered easiest to hardest — every one with a full worked solution. Work through them free, no account needed.
Sample: the first question, solved
A graph shows a line through the origin with slope 5. Which equation represents this direct variation relation?
📘 Worked solution
✓A direct variation has no constant term, so the equation is simply the slope times x.
And one from the hard end
Explain the difference between direct variation (y=kx) and partial variation (y=kx+b).
