Answer: -3

Step-by-step explanation: You have to get the equation into slope intercept form

$3x + y =18\\$

subtract 3x from both sides $y = -3x + 18$

so the slope is -3

Answer:

-3

Step-by-step explanation:

put into the form y=mx+b

y= -3x + 18

"m" is the slope so -3 is the slope

There is a line whose slope is 0 and whose y -intercept is 9. What is its equation in slope-intercept form?

Monica [59]

Answer:

y = 0x + 9

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

here m = 0 and c = 9, hence

y = 0x + 9

The equation of a horizontal line is normally written as y = 9

with the x- term omitted

√(112) - √(80) / √(20) - √(28) = ?

Evgesh-ka [11]

$\large\underline{\sf{Solution-}}$

<u>We need to solve,</u>

$\dfrac{\sqrt{112}-\sqrt{80}}{\sqrt{20}-\sqrt{28}}$

We can write the above mentioned expression as,

$\sf\longmapsto\dfrac{\sqrt{2\times2\times2\times2\times7}-\sqrt{2\times2\times2\times5}}{\sqrt{2\times2\times5}-\sqrt{2\times2\times7}}$

So,

$\sf\longmapsto\dfrac{\sqrt{4\times4\times7}-\sqrt{4\times4\times5}}{\sqrt{2^2\times5}-\sqrt{2^2\times7}}$

So,

$\sf\longmapsto\dfrac{\sqrt{4^2\times7}-\sqrt{4^2\times5}}{\sqrt{2^2\times5}-\sqrt{2^2\times7}}$

Hence,

$\sf\longmapsto\dfrac{4\sqrt{7}-4\sqrt{5}}{2\sqrt{5}-2\sqrt{7}}$

Taking common in respective terms,

$\sf\longmapsto\dfrac{4(\sqrt{7}-\sqrt{5})}{2(\sqrt{5}-\sqrt{7})}$

On cancelling 4 with 2,

$\sf\longmapsto\dfrac{4\!\!\!/^{\:2}(\sqrt{7}-\sqrt{5})}{2\!\!\!/(\sqrt{5}-\sqrt{7})}$

$\sf\longmapsto\dfrac{2(\sqrt{7}-\sqrt{5})}{(\sqrt{5}-\sqrt{7})}$

Taking (-) common,

$\sf\longmapsto\dfrac{-2(\sqrt{5}-\sqrt{7})}{(\sqrt{5}-\sqrt{7})}$

So, (√5 - √7) gets cut,

<u>Hence, </u>

$\longmapsto\bf\dfrac{\sqrt{112}-\sqrt{80}}{\sqrt{20}-\sqrt{28}}=-2$

Solve the equation for y. Show your work. 6x−2y=4

borishaifa [10]

Answer:
y = 3x - 2
General Formulas and Concepts:
Properties of Equality
Step-by-Step Explanation:
Step 1: Define equation
6x - 2y = 4

Step 2: Solve for y
1. Subtract 6x on both sides: -2y = 4 - 6x
2. Divide both sides by -2: y = -2 + 3x
3. Rewrite: y = 3x - 2
