how to find y intercept

[faint kelp]

Depends a lot on the scenario and what the table of points represents.

Table of what, exactly? x-values, y-values, points like (x, y) ?

Any information about the formula? Line, parabola, something else?

If you've got a couple points and know it's a line, then you can construct the line and then determine y-intercept.

If it's more involved, helpers need to know more information to figure out the situation and then how to help. I have to head out now. With more info, someone else should be able to help you.

Yes, you could count down. You could also use the slope and one of the points to get the line equation. Here's a picture I use when dealing with problems like this...

Here's a worked out example for reading off the slope and using one given point to make a quick line.

Well done so far!

Here's a quick check on the line formula:
At {1, 2}, (y - 2) = -7/2 (x-1) is 0 = 0, true. We can plug in {3, -5} to see that it's on this line too.

You can probably guess there are lots of line formulas through 2 points. So once you have one line, you should be able to get the y-intercept.

thanks 🙂 I hope it helps

I'm glad 🙂 Thank you for letting me know

One tip that comes to mind to find y-intercept. Say you've got a line like y = slope x + c for constant c. Or you've got (y - b) = slope * (x - a) for some point on the line given as {a, b}.

If you want the y-intercept, think about the only x-value that matches the y-intercept point: {??, y-intercept value}.

Just plug that x-value into your line formula and simplify.
At that point, the y-intercept should be all yours.

you're welcome 🙂

If it's resolved, I think the command is ".closed" without quotes. Then, the system marks it as resolved.
