It is: y = 2x-6
P=7
It shows the Y Intercept, meaning when it would cross the Y axis, and it also shows the slope of the line, and whether it is downward sloping or upwards.

x+4 = 10 x = 10-4 x = 6
y + 4 = 2x −1

In order to answer that, we need an "equation" that shows us the relationship among 'Y', 'A', and 'B'.

There are several equations; sometimes one can be more appropriate, sometimes another, depending on what data is given. For example, an equation solved for "y", i.e. of the form y = mx + b directly shows you the line's slope (which is "m") and the y-intercept (which is "b"). On the other hand, a general form of an equation of a line is ax + by = c This form is able to represent vertical lines, which can't be expressed with the slope-intercept form. There are several other equations for a line as well.
Such an equation is called a "proportion".

The total ionic equation shows all of the equation, even the spectator ions. The net ionic equation shows the net change after spectator ions have been removed.
