Question

Kyle wants to find the equation of the line that passes through the points (1, –7) and (–1, 1) .

Answer 1

Answer:  Option 'c' is correct.

Step-by-step explanation:

Since we have given that

There are two points as follows:

$(1,-7)\ and\ (-1,1)$

As we know the formula for "Two point slope form":

$m=\frac{y_2-y_1}{x_2-x_1}$

Now, we put the values in the above equation ,

$m=\frac{1+7}{-1-1}\\\\m=\frac{8}{-2}\\\\m=-4$

Now, we use this form "$y=mx+b$ "

So,

$-7=-4(1)+b\\\\-7+4=b\\\\-3=b$

Hence, Option 'c' is correct.
