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

<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>

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