The line of best fit for a scatter plot is shown: What is the equation of this line of best fit in slope-intercept form?
sukhopar [10]
First find the slope.

We know these two points are in the line: (0,8) and (6,5)

\sf Slope = \frac{y_2-y_1}{x_2-x_1} = \frac{8-5}{0-6} = \frac{3}{-6} = \boxed{-\frac{1}{2}}

The slope is -1/2. The y-intercept can be found when x = 0. And we know that the point (0,8) is on the line and x = 0, therefore the y-intercept is 8.

Plugging this into the slope-intercept form which is

y = mx + b, where m is the slope and b is the y-intercept, we get:

y = (-1/2)x + 8

What is the roots of f(x)=-x^2-6x-14
Nutka1998 [239]

Answer:

x=-3\pm i \sqrt{5}

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

<u>Algebra I</u>

  • Standard Form: ax² + bx + c = 0
  • Quadratic Formula: x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}

<u>Algebra II</u>

  • Imaginary roots: √-1 = i

Step-by-step explanation:

<u>Step 1: Define function</u>

f(x) = -x² - 6x - 14

<u>Step 2: Set up</u>

  1. Set equation equal to 0:                    -x² - 6x - 14 = 0
  2. Factor out -1:                                       -(x² + 6x + 14) = 0
  3. Divide both sides by -1:                      x² + 6x + 14 = 0

<u>Step 3: Define variables</u>

a = 1

b = 6

c = 14

<u>Step 4: Find roots</u>

  1. Substitute:                              x=\frac{-6\pm\sqrt{6^2-4(1)(14)} }{2(1)}
  2. Exponents:                             x=\frac{-6\pm\sqrt{36-4(1)(14)} }{2(1)}
  3. Multiply:                                  x=\frac{-6\pm\sqrt{36-56} }{2}
  4. Subtract:                                 x=\frac{-6\pm\sqrt{-20} }{2}
  5. Factor:                                    x=\frac{-6\pm\sqrt{-1} \sqrt{20} }{2}
  6. Simplify:                                  x=\frac{-6\pm2i \sqrt{5} }{2}
  7. Factor:                                    x=\frac{2(-3\pm i \sqrt{5} )}{2}
  8. Divide:                                    x=-3\pm i \sqrt{5}

Billy found the slope of the line through the points (2,5) and (-2,-5) using the equation
Shkiper50 [21]
Slope is calculated as the change in y over the change in x so you would need to do 5- (-5) which turns the negative sign to a positive making it 5+5=10 and the same thing with the 2s 2-(-2)=4 so the answer would be 10/4 or 5/2. Billy did the reciprocal.

In 1955 an antique car that originally cost 3,943 is valued at 64,125 if in excellent condition, winch is 2 1/4 times as much as
nika2105 [10]

Answer:

The value of the car in very nice condition is $28,500.

Step-by-step explanation:

Consider the provided information.

In 1955 an antique car that originally cost 3,943 is valued at 64,125 if in excellent condition, winch is 2 1/4 times as much as a car in very nice condition.

The mixed fraction can be written as:

2 \frac{1}{4}=\frac{9}{4}

Let x is the value of car in very nice condition.

64,125 =\frac{9}{4}x

x=\frac{64,125\times 4}{9}

x=28,500

Hence, the value of the car in very nice condition is $28,500.
