Answer:
y=x
Step-by-step explanation:
First of all let's look at the gradient (slope) of the line.
Gradient = change in y / change in x = (4-2) / (4-2) = 1
Now let's look at the y intercept. If we extend the line going through D and E, we can see that it will go through the origin, so it intercepts y at 0.
Overall the equation will be y = 1(x) + 0
Which simplified is y = x
