So if the area of a square is 320 square meters, then because all four sides are equal, you would end up with the equation
which simplifies to
A: (-4,1), B(1,-3), C(0,2), D(5,0), E(-3,6) F(-4,-5), G(0,-4), H(2,4) I(-2,3), J(5,-2)
Quadrant 1: D, H
Quadrant 2: A, I, E
Quadrant 3: F
Quadrant 4: B, J
on the x axis: D
On the y axis: G, C
Answer:
12. -5 and 4
13. -2 and -1
14. -5 and 6
15. -4 and -3
16. -2 and 8
17. -3 and 8
Step-by-step explanation:
First we have to figure out the slop of the given equation:
-1x+2y+2=0
y=1/2x - 1
So the slope is 1/2. A line perpendicular to this line has a slope of the negative reciprocal of this slope. So the slope of the line you want to find is -2.
So: y +3 = -2(x+3).
And you can expand into the form that you want (or just keep it this way). :)
