The point slope form, , is useful in situations involving slope and the location of one or more points. The standard form, , is usually easier to use when we need to make algebraic calculations. When needs or knowledge change, we can convert an equation from one form into another.
Answer:
eleven and three hundredths.
Step-by-step explanation:
The answer is 230. Good luck
A-y=4.50x ,4.50 is the slope because for each shirt she sells that is how much she makes and she doesn't have an original value for a y-intercept.
B- 1 ,each tee-shirt she makes she will profit 4.50 for a single so she makes money after the first one.
C-129 ,because you need to find how much each tee-shirt costs in the bunch of 70 and divide it from 800 and round to 129.
