Which of these are the intercepts of the graph of y = 3x – 12?

(4, 0), (0, -12)
(12, 0), (0, 4)
(3, 0), (0, 4)
(4, 0), (0, 3)
(-4, 0), (0, -12)

1

x = 1

step-by-step explanation:

0 ÷ x = 0

0 ÷ 1 = 0

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)
