Find the inequality represented by the graph.
Korvikt [17]

Answer:

y>4x-2

Step-by-step explanation:

First let us find the equation of the line.

Given points (1,2) and (0, -2), the slope would be

(2-(-2))/(1-0) = 4/1= 4

The intercept is at -2, so the full equation would be

y=4x-2

However, we need to find the inequality of the graph. Everything greater than our line/above our line is included. Also notice that the line is dotted, which means that the line itself is not included.

Our equations should be,

y>4x-2

<em>I hope this helps! :)</em>

Answer:

5−x²+2xy−y²

Step-by-step explanation:

5 - (x-y)²

Rewrite  

(x−y)² as (x−y)(x−y) so

5−((x−y)(x−y))

Expand (x−y)(x−y) using the FOIL Method

Apply the distributive property.

5−(x(x−y)−y(x−y))

Apply the distributive property

5−(x⋅x+x(−y)−y(x−y))

Apply the distributive property

5−(x⋅x+x(−y)−yx−y(−y))

Simplify and combine like terms  

Simplify each term

5−(x²−xy−yx+y²)

Subtract yx from −xy  

5−(x²−2xy+y²)

Apply the distributive property

5−x²−(−2xy)−y²

Multiply  −2 by −1

5−x²+2xy−y²
