Y = -2X + 3
The graph is a straight line, with a slope of -2, passing through the point Y=3
on the Y-axis.
-- From the point Y=3 on the Y-axis, move 1 to the right and 2 down.
This brings you to the point (1, 1). Mark the point.
-- Place your ruler so that the point Y=3 and the point (1, 1) are both
along the edge.
-- Draw the line, using the ruler's straight edge as a guide.
-- Extend the line as far in either direction as may be helpful.
-2x plus 3y equals 1
y = 2x + 5x - 12 = 7x - 12 So the zero is 12/7 = 1.7143 (approx)

Yes.
Yes.
-2x plus 3y equals 1
Interpreting that function as y=x2+2x+1, the graph of this function would be a parabola that opens upward. It would be equivalent to y=(x+1)2. Its vertex would be at (-1,0) and this vertex would be the parabola's only zero.

y = 2x + 5x - 12 = 7x - 12 So the zero is 12/7 = 1.7143 (approx)
No.
The [ 2x + 1 ] represents a function of 'y' .
Yes.

y = x2 + 2x + 1zeros are:0 = x2 + 2x + 10 = (x + 1)(x + 1)0 = (x + 1)2x = -1So that the graph of the function y = x + 2x + 1 touches the x-axis at x = -1.

Yes.
Yes.
