The cosecant is the reciprocal of the sine, so
![\sin \theta = \dfrac{15}{\sqrt{5}} = 3 \sqrt{5}](https://tex.z-dn.net/?f=%5Csin%20%5Ctheta%20%3D%20%5Cdfrac%7B15%7D%7B%5Csqrt%7B5%7D%7D%20%3D%203%20%5Csqrt%7B5%7D)
That's not the sine of a real angle because it's out of the range -1 to 1.

Parallel graphs have the same slope. perpendicular has opposite reciprocal slopes. These equations have slopes of -2/5 and 25 so they are neither.
Answer:
y = 2x
Step-by-step explanation:
Note the relationship between x and y, that is
x = - 42 → y = - 84 ← that is y = 2x
x = - 14 → y = - 28 ← that is y = 2x
x = 14 → y = 28 ← that is y = 2x
x = 42 → y = 84 ← that is y = 2x
Thus the linear equation is y = 2x
