Astudent found the slope of a line that passes through the points (1,14) and (3,4) to be 5. what mistake did she make?

M = (y2-y1)/(x2-x1)
 = (4-14)/3-1
 = -10/2
 = -5

A. p = 2(l + w)p/2 - l = ww = p/2 - l b. while isolating the variable w in the equation, i first divided both sides by 2 and then i subtracted l from both sides. i hope this .
