Let's start by tidying up that equation and put it into slope-intercept form (y = mx + b); from there, we can plug in coordinates.

Let's use the distributive property on the right side:

Now add 4 to both sides

Which simplifies to:

Since that's the equation of our line, now we can plug in coordinates and see what it churns out.
We know that the x-coordinate of P = 4 so let's substitute 4 in for x and calculate the y-coordinate:



So the y-coordinate for point P =
10
Hi there :) The best way to graph equations and to follow these 3 steps
<span>1. Locate the y-intercept on the graph and plot the point.
2. From this point, use the slope to find a second point and plot it.
3. Draw the line that connects the two points.
Please mark brainliest, thanks!</span>
We can't find explicit values for
and
, since there is only one equation, but two variables.
The best we can do is solve for one variable with respect to the other:
Solve for
:
subtract
from both sides:

divide both sides by
:

Solve for
:
subtract
from both sides:

divide both sides by
:
