Hello!
The midpoint formula is basically an average of x and y.
It is also written as: 
.
With the formula above, we can substitute the given points into the equation, and simplify.
Therefore, the midpoint between points H and J is choice D, (6, 3.5).
Answer:
A
Step-by-step explanation:
The cosine of a right triangle is the adjacent over the hypotenuse. If the cosine is -3/5 then it must be a right triangle with sides 3, 4, & 5 since this is a Pythagorean triple. This means the sin will be -4/5. We know its negative because the tangent is positive so this is the 3rd quadrant where both Sine and Cosine are negative.
