2. The slope of the tangent to a curve at any point (x, y) on the curve is negative 1 times x divided by y . Find the equation of the curve if the point (2, -2) is on the curve. (5 points)
x + y = 0
x2 - y2 = -2
x2 + y2 = 16
x2 + y2 = 8

x + y = 0

Step-by-step explanation:

point (2, - 2) => x = 2 & y = -2

x + y = 2 + (-2) = 2 -2 = 0

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

you,
