Could someone please help me with finding the coordinate pairs of the three circled questions. I can do the graphing on my own

Could Someone Please Help Me With Finding The Coordinate Pairs Of The Three Circled Questions I Can Do The Graphing On My Own class=

When you see how easy this is, you'll smack yourself upside the head.

Take #60.  Those are two lines.

-- One line is x=-5.  That's a vertical line that crosses the x-axis where x=-5, and EVERY POINT on it is at x=-5 no matter what 'y' is at that point.

-- The other line is  y=2.  That's a horizontal line that crosses the y-axis where y=2, and EVERY POINT on it is at y=2 no matter what 'x' is at that point.

So you have the intersection of two lines.  On one of them, 'x' is always -5.  On the other one, 'y' is always 2 .  Now what do you suppose the coordinates will be at the point where they cross ?    Could it possibly be anything different from  (-5, 2) ? ?

In #62:
On the first line, 'y' is always -6.  On the other line, 'x' is always 1.
They MUST intersect  at   (1, -6) . 

In #64:
On one line, 'y' is always -1.  On the other line, 'x' is always zero.
(The line where 'x' is always zero happens to be the y-axis.)
I'm SURE that by now you know where these two lines intersect.

You don't even have to graph any of these to know where they intersect !
You can just look at the problem and the coordinate pair jumps out at you.
