Write an equation of the line passing through the points (4.15) and (-1. - 15).
jolli1 [7]

Answer:

y = 6x - 9

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS

<u>Algebra I</u>

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

Slope-Intercept Form: y = mx + b

  • m - slope
  • b - y-intercept

Step-by-step explanation:

<u>Step 1: Define</u>

Point (4, 15)

Point (-1, -15)

<u>Step 2: Find slope </u><em><u>m</u></em>

  1. Substitute:                    m=\frac{-15-15}{-1-4}
  2. Subtract:                       m=\frac{-30}{-5}
  3. Divide:                          m=6

<u>Step 3: Find y-intercept </u><em><u>b</u></em>

  1. Define:                    y = 6x + b
  2. Substitute:              -15 = 6(-1) + b
  3. Multiply:                  -15 = -6 + b
  4. Isolate <em>b</em>:                 -9 = b
  5. Rewrite:                   b = -9

<u>Step 4: Write linear equation</u>

<em>Substitute in all variables.</em>

y = 6x - 9

And we have our answer!

What is the slope of the secant line? Thank you
Burka [1]

Answer:

Given that,

The function is,

f(x)=1.2x^3-37x^2+265x+555

To find: To find the slope of the secant line from x1=0 and x2=4

Explanation:

First we find the corresponding y values that is y1 and y2 for the given x1 and x2 respectively.

we get,

Whwn x1=0,

y1=f(x1)=f(0)

f(0)=1.2(0)^3-37(0)^2+265(0)+555f(0)=555y1=555

When x2=4, we get,

f(4)=1.2(4)^3-37(4)^2+265(4)+555f(4)=1099.8

To find the slope of the line passing the points (0,555), (4,1099.8)

we know that,

Slope of the line passing through the points (x1,y1) and (x2,y2)

m=\frac{y2-y1}{x2-x1}

we get,

m=\frac{1099.8-555}{4-0}m=\frac{544.8}{4}m=136.2

Answer is:

Slope of the secant line from x1=0 and x2=4 is 136.2.

DUE TOMORROW GIVING BRAINLIEST!
Stells [14]

Answer:

I gotcha.

Step-by-step explanation:

Condensation - water which collects as droplets on a cold surface when humid air is in contact with it.

Pressure - continuous physical force exerted on or against an object by something in contact with it.

Temperature - the degree or intensity of heat present in a substance or object, especially as expressed according to a comparative scale and shown by a thermometer or perceived by touch.

Thermal energy - (also called heat energy) is produced when a rise in temperature causes atoms and molecules to move faster and collide with each other. The energy that comes from the temperature of the heated substance is called thermal energy.
