y=-3X the line would cross the y-axis at (0,0)
rearrange: y = 3x - 3, which crosses the x-axis when y = 0, ie when x = 1
The vertical y axis on the Cartesian plane is both negative and positive
y = 3x + 1 y = 3x + 2 y = 3x + 3 y = 3x
y-3x-3 y=3x+3 A line with a slope of 3 crossing the y-axis at 3.
y=-3X the line would cross the y-axis at (0,0)
rearrange: y = 3x - 3, which crosses the x-axis when y = 0, ie when x = 1
The vertical y axis on the Cartesian plane is both negative and positive
3x - y = 4 Get y by itself to see if it is the same as y = 3x - 4: 3x = 4 + y 3x - 4 = y Therefore, 3x - y = 4 is the equivalent of y = 3x - 4.

your equation is y=3x + 4 here are five parallel equations... y=3x + 5 y=3x + 6 y=3x + 7 y=3x + 8 y=3x + 9
y = 3x + 1 y = 3x + 2 y = 3x + 3 y = 3x
3x-y=9 y=3x-9
3x - y = 12 is the same as 3x - 12 = y, or y = 3x - 12.
y = 2 sin 3x y' = 2(sin 3x)'(3x)' y' = 2(cos 3x)(3) y' = 6 cos 3x
y = 3x 3x + 4y = 30 3x + 4(3x) = 30 3x + 12x = 30 15x = 30 x = 2 y = 3x y = 3(2) y = 6 (2, 6)
