What is the equation of the line in point-slope form?

Mathematics

Answer:

y +500 = -\frac{1}{5}(x - 100)

Step-by-step explanation:

Given

The attached graph

Required

Determine the equation in point slope form

From the graph, we have the following points;

(x_1,y_1) = (-400,-400)

(x_2,y_2) = (100,-500)

First, we calculate the slope (m):

m = \frac{y_2 - y_1}{x_2 - x_1}

m = \frac{-500 - (-400)}{100- (-400)}

m = \frac{-500 +400}{100+400}

m = \frac{-100}{500}

m = -\frac{1}{5}

The equation is then calculated using:

y - y_2 = m(x - x_2)

Substitute x and y values

y - (-500) = -\frac{1}{5}(x - (100))

y +500 = -\frac{1}{5}(x - 100)

Find the area of the trapezoid?
Verdich [7]

Answer: 52.5 units squared

Step-by-step explanation:

The formula to find the area of a trapezoid is, (base1 + base2)/2 * height

So you find out which variable is which

Base 1 = 4

Base 2 = 3

Height = 15

Then plug it into the formula,

(4+3)/2 * 15

Then solve the order of operations

7/2 * 15

3.5 * 15

52.5 is the answer

What is the equation in standard form of the line Y equals 1 / 9 x + 5
Juli2301 [7.4K]

Answer:

1/9x - y = -5

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Equality Properties

<u>Algebra I</u>

Standard Form: Ax + By = C

Slope-Intercept Form: y = mx + b

  • m - slope
  • b - y-intercept

Step-by-step explanation:

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

Slope-Intercept Form:   y = 1/9x + 5

<u>Step 2: Find Standard Form</u>

  1. Subtract 1/9x on both sides:                    -1/9x + y = 5
  2. Multiply -1 on both sides:                         1/9x - y = -5
