What is the midpoint of /fb? a.point a b.point g c.point h d.point l

Midpoint is point l d

Think about what "midpoint" means. the immediate answer is "a point midway (halfway) between two others." if you want to find a point that's halfway between two other points, you'll first need to find the distance between those two points - in this case, points f and b. since f and b are lying on the number line, what we're really asking is what the distance between the  numbers -2 and 8 is. what mathematical operation do you need to find the distance between  two numbers? after you've found that, you'll need to cut that distance in half to find the midpoint. what mathematical operation do you need to find half of a number? once you have that, all you have to do is count that many notches either right of f or left of b, and you'll have your answer.

option (d) i.e. Subtract 11 from both sides
