The slope of the tangent to a curve at any point (x, y) on the curve is -x/y. find the equation of the curve if the point (2,-2) is on the curve a. x+y=0
b. x^2-y^2=-2
c. x^2+y^2=16
d. x^2+y^2=8

All points to the left of zero on a horizontal number line are negative. a number line is a picture of a graduated straight line that serves as abstraction for real numbers. this number line can be extended to the left to represent numbers which are smaller than 0. such numbers are called negative numbersmark me brainliest
