if AC = 20, AE = 4y, and EC = 4, what is the value of y?

Answer 1

Answer:Finding the y value is easy if you know the slope of the line and the x coordinate. Review the equation for the slope of a line. The equation for finding the slope is: m = [y1 - y2] / [x1 - x2]. If you know x, you can solve for y to find the y value for the slope of the line.

Step-by-step explanation:

Answer 2

Answer:

  y = 4

Step-by-step explanation:

Point E is on segment AC such that AC=20, AE=4y, and EC=4. You want the value of y.

Setup

The whole is the sum of the parts of a line segment.

  AC = AE +EC

  20 = 4y +4 . . . . . substitute given values

Solution

Divide by 4

  5 = y +1

  4 = y . . . . . . . . subtract 1

The value of y is 4.
