Get some graph paper.
Draw some axis (x and y)
Solve your equation over and over for each value of x.
3x-4y+4=0
3x+4=4y
(3/4) x = y
So for:
x=1 , y=0.75
x=2 , y=1.5
x=3, y=2.25
x=4, y=3
Now, slightly easier since we actually know from the form of the equation that it's a straight line y=mx+c being the straight line equation. c is where the line hits the y axis (in this case at 0) and m is the "gradient of the line" we actually only need to solve it twice and draw a straight line through the points. I'd suggest x=0 and x=4 as they are nice easy points.
15x minus 8=minus 180 3x+8=24
An equation where x equals 3.
The lines are parallel.
3x+7=2x-5 x=-12
3x - 2x + 4 = 0 3x - 2x = -4 x = -4
3x - 12 = 10x - 15 - 6x -10 3x - 12 = 4x -25 3x + 13 = 4x 13 = 4x - 3x 13 = x None?
15x minus 8=minus 180 3x+8=24
An equation where x equals 3.
The lines are parallel.
3x+7=2x-5 x=-12
4x + 10 + 3x = 40 - 3x 4x + 10 + 3x + 3x = 40 20x = 40 x = 2
2x+3y=13 3x-y=3 x=2
X = -2(13 + y) / 3x = 5y / 4 - 1
3x - 2x + 4 = 0 3x - 2x = -4 x = -4
X=7
First of all, if 'x' is 3, then 'x' doesn't equal -3x+3 . You must mean y = -3x + 3.If x=3, then (-3x + 3) = -6 .The graph is the point (3, -6) .
Let's simplify: f(x) = 3x-3x, so f(x) =0, so y=0 The graph is a line along the x-axis.
