Answer:
m=-4
(the slope is negetive 4)
Step-by-step explanation:
Answer:
[tex]-4[/tex]
Step-by-step explanation:
Start with point-slope form:
[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Identify your values.
[tex]x_1=7\\x_2=8\\y_1=-3\\y_2=-7[/tex]
Substitute.
[tex]\frac{-7-(-3)}{8-7}[/tex]
The [tex]-3[/tex] becomes positive as it is being multiplied by a negative.
[tex]\frac{-7+3}{8-7}[/tex]
Combine like terms.
[tex]\frac{-4}{1}[/tex]
Rewrite.
[tex]-4[/tex]
