A basketball coach plotted data about her shooting guard’s playing time and point scoring in a scatterplot. Shooting Guard Minutes Played and Points Scored A graph has minutes played on the x-axis, and points scored on the y-axis. A line goes through points (8, 6) and (30, 21). Which is the equation of the line of best-fit? y = StartFraction 15 Over 22 EndFraction x + StartFraction 6 Over 11 EndFraction y = StartFraction 15 Over 22 EndFraction x + StartFraction 43 Over 11 EndFraction y = StartFraction 22 Over 15 EndFraction x minus StartFraction 86 Over 15 EndFraction y = StartFraction 22 Over 15 EndFraction x minus four-fifths

72 is the answer to this problem

actually what is a question i don't understand

third choice down

step-by-step explanation:

the first inequality is based on the number of adults and campers, and the second inequality is based on the cost of feeding both the adult and the camper.

we know that there is room for 525 people max.   it's ok to have less than 525, but it's not ok to have more than 525, so the inequality is less than or equal to.   the number combination of adults (x) and campers (y) cannot exceed this 525 max.   therefore:

x + y ≤ 525

now we talk about cost.   it costs $9 to feed one adult, so depending upon the number of adults you have (x) depends upon how much it will cost to feed that number of adults.   same with the campers, who cost $5 to feed.   the adults can be represented by 9x and the campers can be represented by 5y.   since the budget cannot exceed 1,200, the second inequality is:

9x + 5y ≤ 1200
