Write equation of the line containing (-3,4) and (-1,2)

y = - 1x + 1

Step-by-step explanation:

Slope Intercept: y=mx+b

First, find the slope. The formula to find the slope is (y2-y1) / (x2-x1).

So, substituting the values in for x2, x1, y2, and y1, you get (4-2) / (-3 - (-1)).

Simplifying this, you get 2/-2, which is - 1. So, your slope is - 1. To find the y-intercept you plug in values for x and y. Take a random ordered pair given in the problem (imma just use - 1,2). 2 is the y and - 1 is the x. So, your equation would look like this:

2 = - 1 (-1) + b

Solve the equation to get b. B is 1.
