Question

Find the slope of the line that passes through (78, -14) and (12, 25).

Answer 1

Answer:

$\huge \orange{ - \frac{13}{22} }$

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

$m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1}$

From the question we have

$m = \frac{25 - - 14}{12 - 78} = \frac{25 + 14}{ - 66} = - \frac{39}{66} = - \frac{13}{22}$

We have the final answer as

$- \frac{13}{22}$
