Question

Ariel was told the x-intercept and the y-intercept of a line with a
positive slope. Yet, it was impossible for Ariel to find the slope of the
line. What can you conclude about this line? Explain your thinking.

Answer 1

Yes it is possible not to know the slope, if you know the x a y intercepts.

Answer 2

and* not just a

Answer 3

But you need to help me help you.

Answer 4

But why?

Answer 5

What do you need to find the slope of a line?

Answer 6

That is the question....

Answer 7

What do you need?

Do you need one point?
Do you need two points?
Do you need three points?

Answer 8

At least 2 points?

Answer 9

Yes exactly

So you can't find the slope of a line with and single point.

Where on the x/ y axis are the x-intercept and the y-intercept the same point?

Answer 10

Answer 11

Of course it is the origin.

Answer 12
