The formula for finding a gradient is
y2-y1/x2-x1.
So in your case it will be the following:
Answer:
The answer is 1/9.
Step-by-step explanation:
When solving for the slope of a perpendicular line to a given, you have to flip the opposite reciprocal.
First take the number and flip the reciprocal, in this case -9 turns into -1/9.
Then flip the sign, like making a negative to a positive or a positive to a negative. In this case make -1/9 into 1/9
Therefore the answer is 1/9.
