Answer:

y = -5/2x +2

Step-by-step explanation:

you want to get y by itself so you subtract 5x from both sides

2y = -5x + 4

then divide by two

y = -5x + 4 ÷ 2 =

y = -5/2x + 2

(x+1)^2+(x-1)^2-2x(x+2)=0

Answer:

x = 1/2

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

$(x+1)^2+(x-1)^2-2x(x+2)=0$
$x^2 + 2x + 1 + x^2 - 2x + 1 -2x^2 -4x = 0$
$(x^2 + x^2-2x^2) + (2x-2x-4x)+(1+1)=0$
$-4x + 2 = 0$

Step 2: Subtract 2 from both sides.

$-4x + 2 - 2 = 0 - 2$
$-4x = -2$

Step 3: Divide both sides by -4.

$\frac{-4x}{-4} = \frac{-2}{-4}$
$x = \frac{1}{2}$

Step-by-step explanation:

slope :

$slope \: = \: \frac{y2 - y1}{x2 - x1} = \frac{8 - 14}{ - 16 - - 4} = \frac{ - 6}{ - 12} = \frac{1}{2}$ = 0.5
