Question

Find the coordinates of point B on AC such that AB is 1/4 of AC

Answer 1

Find the vertical and horizontal difference between the two given points:

Horizontal  is the Y values: 4 - -4 = 4+4 = 8

Vertical is the X values 7 - -1 = 7+1 = 8

Multiply the changes by the ratio:

Now copy the dot on A 2 places to the left and down 2 places and the dot lands on point (5,2)

8 * 1/4 = 2

Answer 2

AC in the horizontal and vertical direction is 8 units. AB in the horizontal and vertical direction is 1/4 of 8 which is 2 units. To find the coordinates of B on the graph, move 2 units to the left and 2 units down. We lie on the point (5, 2).

Best of Luck!
