Write a linear equation in point slope form the line that goes through (-1,1) and (1,-5).

Option D.

Step-by-step explanation:

The equation of the line in point-slope form is:

Where m is the slope of the line and () is a point of the line.

Given the points (-1,1) and (1,-5), you can find the slope with the formula . Then:

Substitute the slope and the point (-1,1) into  :

ANSWER

D.

EXPLANATION

The point-slope form equation is calculated using the formula:

Where m is the slope, which is calculated using the formula:

Let

and

We substitute the points to obtain;

We also substitute the point and slope to obtain;

Simplify the expression in the parenthesis to get;

The correct choice is D.

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8
