Question

What is the equation of this line in slope-intercept form?

Answer 1

Answer:

B

Step-by-step explanation:

Reminder: slope-intercept form is y=mx+b where m is the slope and b is the y intercept

There are two points given on the line: (-1, 2) and (1, -4)

First, find the slope

Reminder: slope is y2-y1/x2-x1

Substituting the numbers into the equation gives -4-(-2)/1-(-1) which would make m=-3

Now that the slope is found, we can use slope point form

Reminder: slope point form is y-y1=m(x-x1)

Substituting the numbers would give this equation:

y-2=-3(x-(-1))

Simplifying the equation would give y=-3x-1.
