Question

Find the slope of (-9,5) and (-1,7)

Answer 1

Answer:

m = 1/8

Step-by-step explanation:

m = y-y/x-x

m = 5-7/-9-7

m = 1/8

Answer 2

Answer:

$\huge{ \boxed{ \sf{ \frac{1}{4} }}}$

Step-by-step explanation:

$\star{ \sf{ \: Let \: the \: points \: be \: A \: and \: B}}$

$\star{ \sf{ \: A( - 9 \:, 5 \: ) \: \longrightarrow \: { \: (x1 \:, y1)}}}$

$\star{ \sf{ \: B( - 1 \:, 7 \: ) \: \longrightarrow{ ( \: x2 \:, y2)}}}$

$\text{ \underline{ Finding \: the \: slope}} :$

$\boxed{ \sf{Slope = \frac{y2 - y1}{x2 - x1} }}$

$\mapsto{ \sf{Slope = \frac{7 - 5}{ - 1 - ( - 9)}}}$

$\underline{ \text{Remember!}} : \sf{( - ) \times ( - ) = ( + )}$

$\mapsto{ \sf{Slope = \frac{7 - 5}{ -1 + 9}}}$

$\underline{ \text{Remember!}} :$

• The positive integers are always added and posses the positive ( + ) sign.
• The negative integers are always added but posses the negative ( - ) sign.
• The negative and positive integers are always subtracted but posses the sign of the bigger integer.

$\mapsto{ \sf{Slope = \frac{2}{8} }}$

$\mapsto{ \sf{Slope = \frac{1}{4} }}$

Hope I helped!
