To do this equation, there would have to be an = in it. If you mean 5x-2y=4, then:
5x-2y=4
-5x -5x =
-2y=4-5x

y+9=14 subtract 9 from each side to get y by itself y=5
Add (2 y - 1) to both sides to result in x - 1 = 2 y; divide by 2 to result in y = (x - 1)/2.
3x + y = -4 -3x -3x y = - 4 -3x now plug in points!+++To clarify the principle, re-arrange the equation so it reads as "y = [something done to x]" then calculate a table of points for the plot itself.
y = -5x + 9 is the equation of a straight line. It cannot be parallel or perpendicular by itself, you need another line to compare it to.
That statement itself is an equation, and there are an infinite number of (x, y) pairs of numbers that satisfy it. To draw a graph of the equation, draw a straight line that rises toward the right at an angle of 45° and passes through [ y = -1/4 ] on the y-axis. The x-value and y-value of every point on that line satisfy your equation. (And we all know how many points there are on a line. Particularly on a line that has no ends.)
