Answer:

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

Now that we've found your y-intercept, we have the original equation. To find the perpendicular equation, you need the opposite reciprocal of your slope.
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:

Answer:
B
Step-by-step explanation:
Becky travels 0.5 miles per hour faster than Emma.
Emma's speed is 7.5 miles per hour. The slope of y = 8x, which is 8, is Becky's speed.
8 − 7.5 = 0.5 miles per hour faster
