Find the ordered pairs for the x- and y-intercepts of the equation 3x − 2y = 18 and select the appropriate option below.
olasank [31]
<h2>Greetings!</h2>

Answer:

B)

Step-by-step explanation:

Y intercept:

Simply substitute all the x values with 0:

When x = 0:

3(0) - 2y = 18

Move the - 2y over to the other side making it a +2y:

0 = 18 + 2y

Move the +18 over to the other side making it a -18:

-18 = 2y

Divide both sides by 2:

\frac{-18}{2} = \frac{2y}{2}

-9 = y

So y intercept is:

<h3> (0 , -9)</h3>

X - intercept:

Simply substitute all the Y's with 0:

3x - 3(0) = 18

3x = 18

Divide both sides by 3:

\frac{3x}{3}  = \frac{18}{3}

x = 6

So the X intercept is:

<h3>(6 , 0)</h3>

This means that your guess of B is correct.
