Question
19-26 - Intersection Points Do the graphs intersect in the
given viewing rectangle? If they do, how many points of intersec-
tion are there?
19. y = -3x + 6x – 4. y = V7- : [-4, 4] by [–1, 3]
20. y = V49 – x, y = }(41 – 3x); [-8, 8] by [–1, 8]
21. y = 6 – 4x – x, y = 3x + 18; [-6, 2] by [-5, 20]
22. y = x' – 4x, y =x + 5; [-4, 4) by [–15, 15]
23. Graph the circle x + y = 9 by solving for y and graphing
two equations as in Example 3.
