Please help!!!!<br> Write the equation of the given line in slope-intercept form.

Tpy6a [65]

<h3>Answer:</h3>

y = -3x +2

<h3>Step-by-step explanation:</h3>

The y-intercept is at +2, so that is the value of the added constant (b).

The line goes down 3 units for each unit to the right, so the slope (m) is ...

... m = ∆y/∆x = -3/1 = -3

Then in the form ...

... y = mx + b

with m=-3 and b=2, your line's equation is ...

... y = -3x +2

The function y = f (x) is graphed below. What is the average rate of change of the function f(x) on the interval - 1 ≤ x ≤ 3?

jonny [76]

Answer:

$\displaystyle -2$

General Formulas and Concepts:

<u>Pre-Algebra</u>

Order of Operations: BPEMDAS

Brackets
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction

Left to Right

<u>Algebra I</u>

Average Rate of Change: $\displaystyle \frac{f(b) - f(a)}{b - a}$

Step-by-step explanation:

<u>Step 1: Define</u>

Interval -1 ≤ x ≤ 3

a = -1, b = 3

f(a) = f(-1) = 4

f(b) = f(3) = -4

<u>Step 2: Find Average</u>

Substitute in variables [ARC]: $\displaystyle \frac{f(3) - f(-1)}{3 + 1}$
Substitute: $\displaystyle \frac{-4 - 4}{3 + 1}$
[Fraction] Subtract/Add: $\displaystyle \frac{-8}{4}$
[Fraction] Divide: $\displaystyle -2$
