Algebra II

Distance Formula: $\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

P1 (4, -5) → x₁ = 4, y₁ = -5

P2 (3, 3) → x₂ = 3, y₂ = 3

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(3-4)^2+(3--5)^2}$
[Distance] [√Radical] (Parenthesis) Simplify: $\displaystyle d = \sqrt{(3-4)^2+(3+5)^2}$
[Distance] [√Radical] (Parenthesis) Subtract/Add: $\displaystyle d = \sqrt{(-1)^2+(8)^2}$
[Distance] [√Radical] Evaluate exponents: $\displaystyle d = \sqrt{1+64}$
[Distance] [√Radical] Add: $\displaystyle d = \sqrt{65}$

Which inequality is represented by this graph?

Mashcka [7]

Answer: C

Step-by-step explanation:

We can say that the equaiton of the line is -1/6x+1, considering that is in each answer choice. Than main part is the shading and inequality. If you look closely at the graph, the shading line is a dashed/dotted line. This means the shaded part does not equal the actual line. We can eliminate B and D.

Now, we are left with A and C. A is saying y< while C is saying y>. C is the correct answer because if you look at the shading, it it above the line, which is greater than. Therefore, the answer is C.
