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).
