A linear equation ?

ax + by = cThe graph if that equation is a straight line whose slope is (-a/b)and whose y-intercept is (c/b).
(a) y = -3x + 1
graph
-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.
