Question 14 (5 points) The function y = 2 cos 3(x+ 25/3) +1 has a phase shift (or horizontal shift) of
OA) 3
B) 2
OC) -2/3
OD 1

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
