john needs to earn $693 to pay for trip. he finds job that pays $7 per hour and he mows lawns for $9. an hour
a. write an inequality describing his goal in terms of hours at his job, x, and hours mowing lawns, y .
i wrote 7x + 9y = 693., is this correct, if not could you please show me thanks ann
b. to graph the inequality how would i get points?

Reiny
They had asked for an inequality.
Since he needs at least $693 you should have had
7x + 9y ≥ 693
to graph this, I would use the intercepts, (693 divides nicely by both 7 and 9)
for xintercept, let y = 0
7x = 693 , x = 99
for yinterecept , let x = 0
9y = 693, y = 77
so after scaling your graph, plot
(0,77) and (99,0)
draw a solid line (the points on the line are included)
and shade in the region above the line.
