Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
here m = - , hence
y = - x + c ← is the partial equation
To find c substitute (- 3, - 1) into the partial equation
- 1 = 2 + c ⇒ c = - 1 - 2 = - 3
y = - x - 3 ← is the equation of the line
To solve this problem you must apply the proccedure shown below:
You must switch the variables, and then, you must solve for , as following:
Therefore, as you can see, the answer is:
