Answer:
b.
Step-by-step explanation:
The given function is

Recall that the reciprocal of the cosine ratio is the secant ratio.
This implies that;



We take the inverse cosine of both sides to obtain;

The power of 4 means to move the decimal 4 places to the right. 6.3 x 10^4
63000
Slope-intercept you have right:
y=3/4x-7
Point slope form is:
y − y1 = m(x − x1)
so
y +7 = 3/4(x -0)
or
y + 7 = 3/4x
2 is the GCF 3+8k
