I am pretty sure it is a because 2 is half of 4 and 18 is half of 36.

Solve the System and write the solution as an ordered pair. <br><br> 3x+3y=6 <br> 5x-6y=15

Ugo [173]

$\\ \sf\longmapsto 3x+3y=6\dots(1)$

$\\ \sf\longmapsto 5x-6y=15\dots(2)$

Multiply eq(1) by 2 and eq(2) by 1

$\\ \sf\longmapsto 6x+6y=12$

$\\ \sf\longmapsto 5x-6y=15$

Add

$\\ \sf\longmapsto 11x=27$

$\\ \sf\longmapsto x=\dfrac{27}{11}$

Now

Put in eq(1)

$\\ \sf\longmapsto 3\dfrac{27}{11}+3y=6$

$\\ \sf\longmapsto \dfrac{81}{11}+3y=6$

$\\ \sf\longmapsto 3y=6-\dfrac{81}{11}$

$\\ \sf\longmapsto 3y=\dfrac{66-81}{11}$

$\\ \sf\longmapsto 3y=\dfrac{15}{11}$

$\\ \sf\longmapsto y=\dfrac{15}{33}$

How do i find the slope

Elodia [21]

Hi, I'm happy to help!

To find the slope, you need to use the slope formula, where m is the slope:

<u>m=</u> $\frac{y_{2}-y_{1 } }{x_{2} -x_{1} }$ <u></u>

Slope means rise over run, or how much the line rises per the amount the line moves forward. This equation shows the movement from the y points to show <u>rise</u>, over the difference in the x points to show <u>run</u>.

Now, to find the slope we insert our values, starting with our second y point:

<u>m=</u> $\frac{2-y_{1 } }{x_{2} -x_{1} }$ <u></u>

Now insert our first y point:

<u>m=</u> $\frac{2-4 }{x_{2} -x_{1} }$ <u></u>

Now we insert our second x point:

<u>m=</u> $\frac{2-4 }{-3 -x_{1} }$ <u></u>

And finally our first x point:

<u>m=</u> $\frac{2-4 }{-3 -3 }$

Now, we solve:

<u>m=</u> $\frac{-2 }{-6}$

So, our slope is -2/-6, to simplify it, we remove both negatives because they cancel each other out.

<u>m=</u> $\frac{2 }{6}$

Now, we simplify our fraction by dividing the top and bottom by 2:

<u>m=</u> $\frac{1}{3}$ <u></u>

So, our slope is 1/3. This means that for every 1 unit the line rises, it goes to the right 3 units. The y-intercept is where the line hits the y axis.

If the question is asking for slope intercept form for the equation, you use y=mx+b

y represents any y coordinate on your line, m represents your slope (1/3), x represents any x coordinate on your line, and b represents your y-intercept (3).

If you were to insert these values, you would get:

y= $\frac{1}{3}$ x+3

You use this to find what a y coordinate would be so you can draw your line.

For the next equation we do the same thing:

<u>m=</u> $\frac{y_{2}-y_{1 } }{x_{2} -x_{1} }$ <u></u>

Insert our values:

<u>m=</u> $\frac{4-1}{2-(-4)}$ <u></u>

Get rid of the double negative:

<u>m=</u> $\frac{4-1}{2+4}$ <u></u>

Solve:

<u>m=</u> $\frac{3}{6}$ <u></u>

Simplify:

<u>m=</u> $\frac{1}{2}$

Now that we know our slope, let's plug it in to our slope intercept form equation.

y= $\frac{1}{2}$ x+3

I hope this was helpful! Keep learning! :D

Looks to me like y= x + 1
