Answer:
y = -x+10
Explanation:
We have a point at ( 2,8) and a point at ( 4,6)
We can find the slope using
m = ( y2-y1)/(x2-x1)
= ( 6-8)/ ( 4-2)
= -2/2
= -1
The slope is -1
We can see that it intercepts the y axis at 10 ( x=0 point)
Using the slope intercept form y = mx+b where m is the slope and b is the y intercept
y = -x+10
