Question

find the slope of the line that passes through the points (2,1) and (-7,4)

Answer 1

Answer:

$-\frac13$

Step-by-step explanation:

Just the slope, so we can simply apply the definition, as variation in y over the variation in x

$m= \frac{\Delta y}{\Delta x} = \frac{1-4}{2-(-7)} = \frac {-3}{9} = -\frac13$

Answer 2

Answer:

0.222

Step-by-step explanation:

Y2-Y1 ÷ X2-X1

4-2 ÷ -7-2

2÷-9

0.222
