For graphs of parallel lines , the slope is ALWAYS the same, in this case, '-0.5'. However , the constant, '2' in this case, can be any numberyou like.
e.g.
y
= -0.5x + 1,000,000 are parallel lines.
y = -0.5x + 3
For any value of c, y = -0.5x + c will be parallel to y = -0.5x + 2 as they will always have the same gradient.
That's not an equation, so there's nothing to graph. Simple way to tell: There's no "equals" sign in it.
[ y = 2x plus or minus any number ] is parallel to it. [ y = -0.5x plus or minus any number ] is perpendicular to it.
y=b+x+x^2 This is a quadratic equation. The graph is a parabola. The quadratic equation formula or factoring can be used to solve this.
The graph of the equation is a straight line. 'm' is its slope. 'b' is its y-intercept
If a = b then it is a circle; otherwise it is an ellipse.
y = -0.5x plus or minus any number
3x + y = c where c is any constant number of your choice.
-2x plus 3y equals 1
Parallel, the slope of the second equation is 4
The lines are parallel.
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
y=6
That is the standard equation to graph a line.
the graph is moved down 6 units
