Algebra I

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Point-Slope Form: y - y₁ = m(x - x₁)

x₁ - x coordinate
y₁ - y coordinate
m - slope

Step-by-step explanation:

Step 1: Define

Point (-3, 5)

Point (2, -3)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute [SF]: $m=\frac{-3-5}{2+5}$
Subtract/Add: $m=\frac{-8}{7}$

Step 3: Write Equation

Plug in variables into the general form.

y - 5 = -8/7(x + 3)

y + 3 = -8/7(x - 2)

Help. How to solve9d + n = 5r

coldgirl [10]

We want to rewrite the following equation

$9d+n=5r$

With d as a function of the other terms. Let's start by subtracting n from both sides.

$\begin{gathered} 9d+n-n=5r-n \\ 9d=5r-n \end{gathered}$

Now, let's divide both sides by 9.

$\begin{gathered} \frac{9d}{9}=\frac{5r-n}{9} \\ \\ d=\frac{5r-n}{9} \end{gathered}$

And this is our final answer.

Using only the values given in the table for the function f(x) = x^3 - 3x - 2 what is the interval of x-values over which the fu

Nataly [62]

Answer:

3 = 3(x² - 1) We know, any Function f(x) decrease s in interval [a, b] when f'(x) < 0 ... -1 < x < 1. Hence, function f(x) = x³ - 3x - 2 , is decreased in (-1, 1).
