Slope intercept form: y = mx + b
Where m = slope and b = y-intercept.
By looking at the graph, we can see that the line cuts at 1/2 on the y-axis, therefore eliminating option D.
So now we have: y = mx + 1/2
Next, we'll find the slope.
Plug the coordinates into the formula.
So our slope is 5/8 and the y-intercept is 1/2.
Option A is the answer.

Step-by-step explanation:
Actually, those questions require us to develop those equations to derive into trigonometrical equations so that we can unveil them or not. Doing it only two alternatives, the other ones will not result in Trigonometrical Identities.
Examining
A) True
Double angle
B) False,
No further development towards a Trig Identity
C) True
Double Angle Sine Formula
D) False No further development towards a Trig Identity
