Which equation represents the graph of the linear function?
a.
y = 4x + 4
b.
y = 4x − 4
c.
y = −4x + 4
d.
y = −4x − 4

By looking at the graph you can rule out choices C and D because the graph given to you is an increasing linear function and C and D represent functions with a decreasing or negative slope. 

By looking at the picture the slop of the graph seems to be 4/1 (rise/run) so your slope is 4. And your y-intercept looks like its -4 so your answer is B

Sin(a)+cos(a)+cot(a)-1=2(csc(x)+1)
