Answer:
It would be the first answer.
Step-by-step explanation:
y=-2x^2+4x-2
y=-2(-1)^2+4(-1)-2
y=-2(1)-4-2
y=-2-4-2
y=-6-2
y=-8
(-1,-8)

Answer:

Step-by-step explanation:
The line passes through the origin has an equation y = mx
m - slope
The formula of a slope of a line passes through the origin
and a point (x, y):

We have the point (6, 8). Substitute:

Finally:

That is coordinates, when I got that in school I had to do up a table abt it and do a graph
Answer:
Ratio of triangle AMN to square ABCD = 1/8
Step-by-step explanation:
area AMN = Area ABN - Area MNB
Where AB = BC = x
Area AMN = [ ½ *( x * ½x )] - [ ½( ½x * ½x)] = x²/8
Area of ABCD = x* x = x²
So therefore:
The ratio of area of triangle AMN to area of square ABCD would be
= (x²/8) / x²
=1/8
