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>

Subtract 3x on both sides: -2y - 6 = -3x
Add 6 on both sides: -2y = -3x + 6
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

What is the slope intercept from for 16x+9y=40

Doss [256]

Answer:

$y = (- \frac{16}{9})x + \frac{40}{9}$ is the slope intercept form for 16x+9y=40

Step-by-step explanation:

Here, the given equation is 16 x + 9 y = 40

Now, the slope intercept form of an equation is y = mx + c,

here m = slope of the equation, b = y - intercept

So, now 16x + 9y = 40 on simplification gives

9y = 40 - 16x

or $y = \frac{40 - 16x}{9} = \frac{40}{9} - \frac{16x}{9}$

or, $y = (- \frac{16}{9})x + \frac{40}{9}$ is the slope intercept form of the given equation.

Here, m = (-16/9) and y- intercept = 40/9
