What is the distance between the points (–4, 7) and (–7, 8)? Round your answer to the nearest tenth. A. 3.2 units B. 4.0 units C. 11.0 units D. 18.6 units
So, use the distance between two points formula:squareroot((x2-x1)^2+(y2-y1)^2) squareroot((-7--4)^2+(8-7)^2) squareroot((-3)^2+(1)^2) squareroot((9+1) squareroot(10) squareroot 10 can be simplified to 3.2 units
