Distance Midpoint Point of Division 1) Identify formula 2) Label coordinates 3) Write Formula 4) Plug numbers into the formula 5) Bedmas Show all your steps Don't erase work

When you are asked how far the length distance Distance formula the distance from A to B A (x1,y1) B(x2,y2) Be careful using order of operations brackets first exponents next then add then square root

When asked to find the coordinates of a point in the middle Midpoint Formula Find the coordinates of the point half way between A(x1,y1) and B(x2,y2). M (xm, ym)

When asked to find a point part way Find the coordiantes of P (xp, yp) Point of Division P A B It is very important that A is the starting point

Example Find the point of the way from (10, 25) to (90, 65) 1) asking for point of division 2) label coordinates 3) 4) Plug in values 5) Bedmas

The point divides the line into a 7:2 If the ratio is given change it into a fraction m:n If the ration is 7:2 the fraction will be The point divides the line into a 7:2 ratio along the line AB. What are the points coordinates if point A is at (75, 8) and point b is (3, 98) xp = 75 + 7/9(3-75) = 19 yp = 8 + 7/9(98 - 8) = 78 Pull
