Answer:

Is there more information? There is not enough to find the slope of a line. I'll answer with an equation that works, but I suspect it won't be correct.

Explanation:

If the only requirement is to have a line that goes through (4,3). Then one could simply say:

y = 4

This is a horizonal line that goes through (3,4), and will always produce a y value of 4 regardless of x. No, it will not pass through (4,3) since y is aleways 4, regardless of x.

If you wanted to get fancier, we could write a needlessly more complex equation:

y = (4/3)x

When x = 3, y = 4, so (3,4) is on this line. But (4,3) is not. y = (4/3)(4) means y = (16/3), not 4.
