Answer: Option 'c' is correct.
Step-by-step explanation:
Since we have given that
There are two points as follows:
[tex](1,-7)\ and\ (-1,1)[/tex]
As we know the formula for "Two point slope form":
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Now, we put the values in the above equation ,
[tex]m=\frac{1+7}{-1-1}\\\\m=\frac{8}{-2}\\\\m=-4[/tex]
Now, we use this form "[tex]y=mx+b[/tex] "
So,
[tex]-7=-4(1)+b\\\\-7+4=b\\\\-3=b[/tex]
Hence, Option 'c' is correct.
