Point slope formula: y-y1=m(x-x1). Answer: y-7=6(x-(-4))
The answer to your question is C
Multiply 9 and 5 then multiply by .5 giving you 22.5 so I’d say that’s your best option
A is the answer because it is the widest variety
It's obviously none of the above because the true area will have a square root of 3 in it because of the equilateral triangle. They want us to find the approximate area. When I was in school the difference between an approximation and the exact answer was greatly stressed but that seems to be fading of late.
That's a rectangle less an equilateral triangle. The area of an equilateral triangle is
which is easily derived but I won't bother here.

Answer: b
