Answer:

It is a horizontal line. The slope = 0.

The line cuts the y-axis at the point

(0,9)

Step-by-step explanation:

y=9

is the equation of a horizontal line. The slope is 0.

If we write it in slope-intercept form we will have:

y=0x+9

This means that for any value of x

that is chosen, the y-value is always 9 Hence y

x=9.

The y-intercept is at the point

(0,9)

What is the solution of -83=b/4? (with work please)

Dvinal [7]

Hi!

<h3>We need to isolate b on one side. </h3>

<em>Multiply by 4 on both sides. </em>

-83 * 4 = b/4 * 4

<h2>The answer is b = -332</h2>

<em>To check your answer, put in the value of b. </em>

-83 = -332/4

-83 = -83

<u>This equation is correct. </u>

Hope this helps! :)

Solve the following equation for a. 5b + 6a – 7 = 2b + 9a

katrin [286]

Answer:

$a=\dfrac{3b-7}{3}$

Step-by-step explanation:

Given that,

The given equation is :

5b + 6a – 7 = 2b + 9a

We need to solve the above equation for a. Taking he terms having a and b in LHS and constants in RHS.

5b+6a-2b-9a=7

taking like terms together

(6a-9a)+(5b-2b)=7

-3a+3b=7

Subtracting both sides by 3b. So,

-3a+3b-3b=7-3b

-3a=7-3b

Dioviding both sides by (-3). So,

$a=\dfrac{7-3b}{-3}\\\\a=\dfrac{3b-7}{3}$

Hence, the value of a is $a=\dfrac{3b-7}{3}$ .
