You'd think that by my FOURTH child I'd know all these algebra problems. Gaaaaah!
For each equation, tell whether its graph is a horizontal or a vertical line. (typo in the math book. I may not know math but I can punctuate)
x=4
I assumed that Y is zero in which case any question that asks for X is horizontal and any question that asks Y is vertical. It doesn't make sense any other way but the problem is we've checked the odd questions in the back of the book and the theory does not hold. On top of that we need to graph more equations that we are clearly doing wrong so that means at least 4 wrong answers. ahhhhhhh
Take made up points on the graph for y and graph it that way. For example: (4,4), (4,-2), (4,6). I think you need at least 3. See what the line looks like. That's how we did it with my son.

That's the problem. All it says is x=4 or y=-7
They want her to draw the line or at least know what the line looks like when all they've provided is one point. You need at least two points to make a line. I thought I knew what the other point was (zero) but then I checked it by an answer that they'd given and my way and their way can't both be right.
Meh, we've moved on. Writing is so much more enjoyable.

This is a vertical line. If x=4 then it's any point Y along that line. And I don't see a typo in the problem?
