The correct answer is the first one. a=(2A/h)-b
Answer:
you use the distance formula: square root of (x2-x1)^2 + (y2-y1)^2. it is a little hard to type the equation out so I reccomend you look up the distance formula and plug the given coordinates into it
A, it’s easy to know because -3 represents the start point in the Y axis. It starts at -3, 2x is the rise/run you move up 2 spaces and then move 1 to the right because it’s positive
13. A=(-1,3) 14.m= (-4,1)
