Hi there & welcome to brainly!
Answer:
[tex] \huge{ \boxed{ \bold{ \tt{ \frac{ - 3}{7} }}}}[/tex]
Step-by-step explanation:
[tex] \text{Let \: the \: points \: be \: A \: and \: B}[/tex]
[tex] \rm{ A(1 \:, 7) \longrightarrow \: (x1 \:, y1)}[/tex]
[tex] \rm{B(8 \:, 4) \longrightarrow \: (x2 \: ,y2)}[/tex]
[tex] \underline{ \text{Finding \: the \: slope \: }} : [/tex]
[tex] \boxed{ \rm{slope = \frac{y2 - y1}{x - x1} }}[/tex]
[tex] \rm{↦slope = \frac{4 - 7}{8 - 1} }[/tex]
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.
[tex] \rm{↦ \: slope \: = \boxed{ \frac{ - 3}{7} }}[/tex]
Hope I helped!
Best regards! :D
