This is a really hard question. I can’t help you
Use point-slope form.
But first let's find the slope.
(4, 2), (2, 4)
m = y2-y1/x2-x1
m = (4 - 2)/(2 - 4)
m = 2/-2
m = -1
So this is the slope, now we can plug this into the equation along with any point.
y - y1 = m(x - x1)
Where y1 is the y-value of the point, x1 is the x-value, and 'm' is the slope.
Let's plug in point (4, 2):
y - 2 = -1(x - 4)
This can be one of your options.
Distribute -1:
y - 2 = -x + 4
Add 2 to both sides:
y = -x + 6
This can be another of your options.
Add 'x' to both sides:
x + y = 6
This can be another of your options.
