Answer:
y = -x + 10
Step-by-step explanation:
The equation can be written in the form
y= mx + c
where m is slope and c is y-intercept
Slope m;
m = y2-y1/x2-x1 = (2-4)/(8-6) = -2/2 = -1
So the equation is now
y = -x + c
we need to get the y-intercept
To get this we can use any of the given points
4 = -6 + c
c = 4 + 6 = 10
So the relationship will be;
y = -x + 10
