PLEASE HELP I GIVE THANKS
ohaa [14]

Take one of the points in the table,

like  x=1  y=5
or    x=2  y=7

Write them into one of the choices on the list,
and see if the result is true.

For example,

-- Take the line in table that says   x=1   y=5.

-- And take the first choice on the list     y = x + 3 .

-- Write '1' in place of 'x', and write '5' in place of 'y'.

-- Then you have    <u>5 = 1 + 3</u> .

Is this true ?  I don't think so.
So the first choice on the list can't be correct.

Try thesame point    x=1   y=5   with  the other choices.
You'll find one that IS correct, and that's the answer.

Answer two questions please
stepladder [879]

Answer:

<em>3. x = 8</em>

<em>4. lines r and s</em>

Step-by-step explanation:

3.

The angles shown are same side interior angles, so they are supplementary. Their measures add to 180 deg.

5x + 10 + 130 = 180

5x + 140 = 180

5x = 40

x = 8

4.

Lines r and s are cut by a transversal, line l. Angles 3 and 6 are alternate interior angles. Lines r and s are parallel.
