Question

A line passes through the points (1, 2) and (4, 4). What is the slope of the line?

Answer 1

-3/-2 ?

Answer 2

M=y2-y1/x2-x1
Here (x1,y1)=(1,2)
(X2,y2)=(4,4)

Just put them into the formula and get the answer

Answer 3

\[\frac{4-2}{4-1}=\frac{2}{3} \]

Answer 4

the slope of a line is the ratio of the change in y with the change in x
to find the change get the difference in the values
given 2 points (x1, y1) and (x2, y2) the slope is (y2 - y1)/ (x2-x1)
