 student found the slope of a line that passes through the points (1, 14)and (3, 4) to be 5. What mistake did she make?
vladimir2022 [97]
Y2-y1/x2-x1
(1,14) & (3,4)
y2= 4
y1=14
x2=3
x1=1

So....

(4-14)/(3-1) = -10/2 = -5

The answer should be negative instead of positive, she probably subtracted 4 from 14 instead.
