Two non-parallel straight lines have an intersection somewhere: With some simple math from highschool you know that f₁(x) = 3 + x and f₂(x) = 5 - x intersect at (1, 4). If you want to draw f₁ you will start with placing dots at (0, 3) and (-3, 0) and then draw a a line through it, and the same for f₂ at (5, 0) and (0, 5). The lines then will cross at (1, 4).
