SUMMARY
The discussion centers on determining the correct representation of a point on a curve, specifically in the context of a mathematical problem involving coordinates. The correct format for a point is emphasized as (x, y), with an example given as (0.693, 2.772). Additionally, a common mistake in rewriting the equation 2x + y = 5 is highlighted, clarifying that it should be expressed as y = -2x + 5 to identify the slope correctly.

A point (in the context of this problem) has two coordinates, so the answer should be in the form of (x, y).ttpp1124 said:

So I'd leave my final answer as (0.693,2.772)?Mark44 said:

You have a mistake right off the bat. 2x + y = 5 is not equivalent to y = 2x + 5.ttpp1124 said:

Instead of solving for the intercepts of the line and doing the slope formula, just rewrite the equation of the line in the form ##y=mx+b## then the coefficient ##m## of ##x## is the slope.
