Amira is writing a coordinate proof to show that the area of a triangle created by joining the midpoints of an isosceles triangles is one-fourth the area of the isosceles triangle. She starts by assigning coordinates as given.Triangle D E F in the coordinate plane so that vertex D is at the origin and is labeled 0 comma 0, vertex E is in the first quadrant and is labeled 2 a comma 2 b, and vertex F is on the positive side of the x-axis and is labeled 4a comma 0. Point Q is between points D and E. Point R is between points E and F. Point P is between points D and F and is labeled 2 a comma 0.Enter your answers, in simplest form, in the boxes to complete the coordinate proof.Point Q is the midpoint of DE¯¯¯¯¯ , so the coordinates of point Q are (a, b) .Point R is the midpoint of FE¯¯¯¯¯ , so the coordinates of point R are (, b).In △DEF , the length of the base, DF¯¯¯¯¯ , is , and the height is 2b, so its area is .In △QRP , the length of the base, QR¯¯¯¯¯ , is , and the height is b, so its area is ab .Comparing the expressions for the areas proves that the area of the triangle created by joining the midpoints of an isosceles triangle is one-fourth the area of the

Eric traveled to two cities on a single highway. The total distance one way was 200 miles. The distance from his original location to the first city was 40 miles less than the distance from the first city to the second city. Suppose that x represents the distance from the original location to the first city and y represents the distance from the first city to the second city. The following system of equations represents the given situation. x + y = 200 x = y − 40 Which pair of coordinates represents the solution (in miles) to this system of equations? (70, 130) (80, 120) (160, 120) (100, 100) (140, 60)
