2Y + 3 = 4
2Y = 4 - 3
Y = 2 - 3/2
Y = 4/2 - 3/2
Y = 1/2

This is a horizontal equation where a line runs from negative infinity to positive infinity at the above.
-2x plus 3y equals 1
y = -0.5x plus or minus any number
A linear equation ?
Same way you graph y = -4x - 0.5
That's not an equation, so there's nothing to graph. Simple way to tell: There's no "equals" sign in it.
y=6
answer is 1
That is the standard equation to graph a line.
the graph is moved down 6 units

The slope of the line that represents the graph of that equation is 15.
They are the same equation just written differently so they are both easy to graph.
