I need help on this it’s a test

the answer is a, y=1/4 + x

Step-by-step explanation:

It is y=4x

Step-by-step explanation:

The coordinates are

(1,4)

(2,8)

and so on. If you plug them into each equation you can see if it is equal to what they y is. I'm not sure if what I said makes sense...

Hope it helps!!

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)

multiply each one by 3.14
