Solve problems by interpreting graphs of linear and non-linear relations, including problems involving direct and partial variation
30 tutor-authored questions for this Ontario curriculum expectation, ordered easiest to hardest, every one with a full worked solution. Work through all 30 with your weekly-lesson access code.
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
"A shipping company charges a $5 handling fee even at zero weight, then $2/kg. Determine the equation of this partial variation relation, and find the cost for 12kg."
