Answer:
Step-by-step explanation:
From the given equation, you can use - 2 immediately. That is an integer in front of the variable x. It is also the slope of the line. So far what you know is
y = mx + b
y = -2x + b
The given point will be used to determine b, which is the y intercept.
x = 1/2
y = - 2
y = -2x + b Substitute the point values into the partial equation
-2 = -2*1/2 + b
-2 = -1 +b Add 1 to both sides
-2+1 = b
b = - 1
So the answer to your question is
y = -2x - 1
