Write the equation of the line graphed below

y= -1

Step-by-step explanation:

I think mainly because it's on the Y axis (horizontal line) on the negative so it would be ethical for that to be the answer

A) tan Y = 7/4; tan Z = 4/7

Step-by-step explanation:

The tangent ratio is opposite/adjacent.

The tangent of angle Y is the side opposite Y, 7, over the side adjacent Y, 4; this gives us tan Y = 7/4.

The tangent of angle Z is the side opposite Z, 4, over the side adjacent Z, 7; this gives us tan Z = 4/7.
