Answer:
B
Step-by-step explanation:
Using the trig. identity
cos x = 
Given
secx = -
, then
cos x = -
×
= -
= -
, thus
x =
(-
) =
→ B
Answer:
Step-by-step explanation:
The functions are written in slope-intercept form.
The graph crosses the y-axis at (0,-2), so the y-intercept is -2.
You can eliminate D because its y-intercept is +2, not -2.
(1,1) and (0,-2) are points on the line.
The slope of the line is (-2-1)/(0-1) = 3
You can eliminate B because its slope is ⅓.
Eliminate C because its slope is -3, not 3.
