Answer:
A
Step-by-step explanation:
tan theta will equal zero if theta = n × pi where n is an integer
Y = -1/2x + 6.....the slope is -1/2 and the y int = 6 or (0,6)
y - y1 = m(x - x1)
slope(m) = -1/2
(0,6)....x1 = 0 and y1 = 6
now we sub
y - 6 = -1/2(x - 0) <==
** You basically just label ur variables and sub them into the point slope form
Dont know a but b is
75=100-2p
75 minus 100 = -25=-2p
-25/-2= p
p=$12.50
He can use it to make sure he lined his place values up properly
