Question

What is the slope of a line that passes through 2,12 and -1,3

Hint: think rise over run

Answer 1

2= x1
12=y1
-1=x2
3=y2

\[\frac{ y2-y1 }{ x2-x1 } \]

Answer 2

(3-12)/(-1-2)=-9/-3=3
slope=(y2-y1)/(x2-x1)

Answer 3

\[\frac{ 3-12 }{ -1-2 }\]

Answer 4

\[\frac{ -9 }{ -3 }\] = \[\frac{ 9 }{ 3 } = 3\]

Answer 5

Therefore, the slope equals 3.
