What is the gradient of a line with an equation of 3x-2y-6=0​
Genrish500 [490]

Answer:

Slope <em>m</em> = 3/2

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Equality Properties

<u>Algebra I</u>

Slope-Intercept Form: y = mx + b

  • m - slope
  • b - y-intercept

Step-by-step explanation:

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

3x - 2y - 6 = 0

<u>Step 2: Rewrite</u>

<em>Find slope-intercept form</em>

  1. Subtract 3x on both sides:                    -2y - 6 = -3x
  2. Add 6 on both sides:                             -2y = -3x + 6
  3. Divide -2 on both sides:                         y = 3/2x - 3

<u>Step 3: Break Function</u>

<em>Identify Parts.</em>

Slope <em>m</em> = 3/2

y-intercept <em>b</em> = -3

A train is pulling 23 red cars and 36 blue cars. Each car has 32 boxes of freight. Which is the best estimate for the number of
Len [333]

So the train is pulling about 50 cars in total, and there's about 30 boxes of freight in each car.


30 x 50 = 1500


The best estimate would be near 1500 boxes of freight through the whole train.

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

Theory - Roots of a product

3.1    A product of several terms equals zero.  

When a product of two or more terms equals zero, then at least one of the terms must be zero.  

We shall now solve each term = 0 separately  

In other words, we are going to solve as many equations as there are terms in the product  

Any solution of term = 0 solves product = 0 as well.

Solving a Single Variable Equation:

3.2      Solve  :    x = 0  

 Solution is  x = 0

Equation of a Straight Line

3.3     Solve   f+x+3  = 0

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  f+x+3  = 0 and calculate its properties

Graph of a Straight Line :

 

 

Calculate the Y-Intercept :

Notice that when x = 0 the value of f is -3/1 so this line "cuts" the f axis at f=-3.00000

 f-intercept = -3/1  = -3.00000  

Calculate the X-Intercept :

When f = 0 the value of x is -3/1 Our line therefore "cuts" the x axis at x=-3.00000

 x-intercept = -3/1  = -3.00000  

Calculate the Slope :

Slope is defined as the change in f divided by the change in x. We note that for x=0, the value of f is -3.000 and for x=2.000, the value of f is -5.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -5.000 - (-3.000) = -2.000 in f. (The change in f is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

   Slope     = -2.000/2.000 = -1.000  

Geometric figure: Straight Line

 Slope = -2.000/2.000 = -1.000

 x-intercept = -3/1 = -3.00000

 f-intercept = -3/1 = -3.00000

x = 0
