Answer:
Step-by-step explanation:
If XY bisects DF at point E, then DE = EF.
Given DE = 2y and EF = 8y-3
2y = 8y-3
subtract 8y from both sides
2y-8y = 8y-8y-3
-6y = -3
y = 3/6
y = 1/2
y = 0.5
DF = DE+EF
DF= 2y+8y-3
DF = 10y - 3
DF = 10(0.5)-3
DF = 5-3
DF = 2
(3) y= 5x+ 13
you have to do the rise (ryse - with a y because it is the y value) over the run to get your slope and then subtract your slope from 18 to get 13.
