Intersections of Lines and Lines
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
Two lines have direction vectors (2,3) and (4,6). What is true about them?
📘 Worked solution
✓(4,6)=2×(2,3), so the direction vectors are scalar multiples - the lines are parallel.
And one from the hard end
"Find the angle between r=(1,2)+t(3,4) and r=(0,1)+s(1,−2), using their direction vectors."
