The table shows the cost of buying x tickets to a school play. Buying Tickets Number of Tickets, x 2 5 10 13 Cost, y $8.50 $21.25 $42.50 $55.25 If the data are graphed on a coordinate grid, what is the y-intercept of the line that passes through thes points?

y-intercept is zero

Step-by-step explanation:

The general equation of the line passing through the points is

y = mx + b

where m is the slope and b is the y-intercept

We can pick any two points to get the slope of the line;

m = (55.25-8.5)/(13-2) = 46.75/11 = 4.25

So partially , the equation will be;

y = 4.25x + b

To get b , substitute any point and use its x and y values

We have (2,8.5)

8.5 = 4.25(2) + b

b = 8.5-8.5

b = 0

-232

step-by-step explanation:

the monthly balance will be $75,000
