CAN SOMEONE PLEASE HELP MEE???

C.

Step-by-step explanation:

All linear equations reflect that the line graph is the straight line.

The linear equation reflecting a straight line has the formula as following:

According to the table, the line graph cross four points: A (-3; -1); B(0;0); C(3;1); D(6;2), which means that the x, y of each point would fit the equation.

So that, we replace the x, y of each point in the equation and have:

1) -1 = a*-3 +b

2) 0 = b

3) 1 = a*3 + b

4) 2 = a*6 + b

From these 4 equations, it can be calculated that: a = 1/3; b = 0

So that the linear equation corresponds to the line graph is:

hope this !

step-by-step explanation:

d = distance between moon and sun, which in this problem is the hypotenuse of a right triangle.  

the distance y is the side opposite to angle x in the right triangle.   use the definition of the sine function from basic trigonometry.

sin(x) = y/d ⇒

d = y/sin(x)
