Answer t What is the slope of the line graphed below?his question…
Parallel lines have the same slope. So if you know the slope of a line in question, or you can calculate it, then you know the slope of any line parallel to that line.
well the rate of change is how much something changes in a matter of time, so it can be graphed in a slope because slopes can represent changes ( negative and positive, zero and undefined)
if the line slants down (from left to right) then it is negative. if the line slants up (from left to right) then it is positive. horisontal lines have a slope of "0" and and vertical ones are undefined.
Any compound inequality, in one variable, can be graphed on the number line.
