It is a straight line equation whereas m is the slope and b is the y intercept.
-2x plus 3y equals 1
Same way you graph y = -4x - 0.5
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.
ax + by = cThe graph if that equation is a straight line whose slope is (-a/b)and whose y-intercept is (c/b).
The equation you have given, y + 2 = 7, does not describe a line, it describes the number 5. You would not graph a single number, there is nothing to 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.
answer is 1
That is the standard equation to graph a line.
y=6
