Answer 1

if you were to draw a line that passes through D and E

Answer 2

what would be the slope ?

Answer 3

i have no clue

Answer 4

since i dont know can you tell me

Answer 5

D=(2,2)
E=(4,4)

Answer 6

right?

Answer 7

For D, when y=2, x also equals 2.
For E, when y=4, x also equals 4

Answer 8

so generally, the equation of the line is y=x
since whatever the value of y, is also the same value of x.
