True or False

In using a graphing utility to solve an

equation, exact solutions are always obtained.

Plot the points (0,3),(1,3),(-2,3),(5,3),and (-4,3). Describe the set of all points of the form (x,3), where x is a real number.

Which of the following equations might have the graph shown? (More than one answer is possible.)

(a)2x+3y=6(b)2x-3y=6(c)3x+4y=12(d)x-y=1(e)x-y=-1(f)y=-2x-1(g)y=-12x+10(h)y=x+4

True or False The distance between two points is sometimes a negative number.

In Problem 17-36, solve each equation algebraically. Verify your solution using a graphing utility.
