Step-by-step explanation:
Given the slope and another point, simply plug them into the point-slope formula to find your y-intercept.

To find the 'opposite,' change your slope's sign. Since your slope is positive , the opposite is
.
To find the 'reciprocal,' flip your fraction. This will make your slope .
Your final equation is:
