Lines<span> that are </span>vertical<span> have no </span>slope<span> (it </span>does not exist<span>). </span>Vertical lines<span> have "rise", but no "run". The rise/run formula for </span>slope<span> always has a zero denominator and is undefined. The equations for these </span>lines describe<span> what is happening to the x-coordinates.</span>
The slope-intercept form:
y = mx + b
m - slope
b - y-intercept
-------------------------------------
2x + y = -3 <em>subtract 2x from both sides</em>
y = -2x - 3
-2y = 6 + 4x
-2y = 4x + 6 <em>divide both sides by (-2)</em>
y = -2x - 3
We have the same equations. Therefore the system of equations is dependent. Has an infinite number of solutions
x ∈ R
y = -2x - 3

Answer:
its IJ
Step-by-step explanation:
well, its obvious buddy, its asking which line is REFLECTED on the X-AXIS, which is the horizontal line across the screen. (think of the sun setting on the horizon).
so like a mirror, it should be the opposite side and not reflected across the Y-AXIS. hope this helps 6th/5th grader...
