The y intercept is when x = 0 so it is:-
8(0) + y = 8
0 + y = 8
y = 6 <------- y-interdept
x intercept is when y = 0 so:-
8x + 0 = 8
x = 1 <-------- x intercept
Here the graph y=x²
Taking the 1st derivative here of the y it will be
y1 = 2x
m=-1/3
That is m=2x
so x=-1/6
so y=(-1/6)²=1/36
So the coordinate of point will be=(-1/6 , 1/36)
Answer is 73 because blah blah blah blah
