Describe the location of the point having the following coordinates. nonzero abscissa, negative ordinate

a graph can be divided into 4 quadrants.

a nonzero abscissa lies on the x axis in the first and second quadrants.

a negative ordinate lies on the y axis in the third and fourth quadrants.

answer: 0.1,0.85

step-by-step explanation:

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
