Write an equation of the line that passes through the given points.
(-1,5) and (2,-7)
pls i need for the question

The slope intercept formula is:

y = mx + b

m is the slope

b is the y-intercept

Let's first find slope:

The formula for slope is

In this case we have the points (-1, 5) and (2, -7)

^^^Plug these numbers into the formula for slope...

-4

^^^This is your slope

So far you have the equation:

y = -4x + b

Now we must find b

To do that you must plug in a point the line goes through in the x and y of the equation. This is the one I have chosen:

(-1, 5)

5 = -4(-1) + b

5 = 4 + b

1 = b

y = -4x + 1

Hope this helped!
