Y = 2x + 1
The [ 2x + 1 ] represents a function of 'y' .
x = 1, y = 0
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.
There are no common points for the following two equations: y = 2x + 3 y = 2x - 1 If you graph the two lines, since they have the same slope, they are parallel - they will never cross.
Y = 2X + 1 Now it is.
No they are parallel.
They are parallel.
The lines are parallel, but not the same.
y = 2x + 1 IS a linear equation!
The y intercept is 1
x = 1 and y = -2
X = 0 (zero) Y = -1 (neg 1)
