Answer:-
To find the number that best represents the slope of a graphed line, use the slope formula: ???? = ???? 2 − ???? 1 ???? 2 − ???? 1 m= x 2 ? −x 1 ? y 2 ? −y 1 ? ? Choose two points on the line, ( ???? 1 , ???? 1 ) (x 1 ? ,y 1 ? ) and ( ???? 2 , ???? 2 ) (x 2 ? ,y 2 ? ), then subtract their coordinates and divide. If the line rises from left to right, the slope is positive; if it falls, the slope is negative. A steeper line has a greater slope magnitude. If the line is horizontal, the slope is 0; if vertical, the slope is undefined.
