Answer:

y = \frac{-3}{2}x -- 2

Step-by-step explanation

We need to fill out the formula y = mx + b.

First, we must find out what each part of that formula means.

mx = slope

b = y-intercept

y = solution (Always unknown)

We already know the slope of the formula, so we can fill that out.

y = \frac{-3}{2}x + b

If it has a slope of -3/2, then that means it is moving down 3 points and moving  to the right 2 points to find the next line. because rise over run.

If it passes through the point (-4, 4) then from their subtract 3 to 4, and 2 to -4.

This means the next point it will reach is (-2, 1). Once again, subtract 3 from 1, and add 2 to -2.

The next point it will reach is (0, -2) This gives us the y-intercept of the equation.

Now we can fill out the rest of the formula!

y = \frac{-3}{2}x -- 2

Factorise (x+y)^2-(4-x)^2​
vovikov84 [41]

Answer:

by using the identity a square - b square = (a+b)*(a-b)

a = x+y

b=4-x

= (x+y + 4-x)(x+y - 4-x)

y+4 * x+y -4+x

y+4*2x+y-4

2xy+y square -4y + yx + 4x + 4y - 16 +4x

3xy +y square + 8x -16
