Point-slope form is:

y - y = m(x - x)

Slope-intercept form is:

y = mx + b

First we need to find the slope. Perpendicular lines have opposite reciprocal slopes, so we need to flip the fraction and multiply by -1. The slope of the given line is 1/5, so the new slope will be -5.

Now put it in point-slope form.

y - (-3) = -5(x - 8)

y + 3 = -5(x - 8)

Now for slope-intercept form, solve for y.

y + 3 = -5x + 40

y = -5x + 37

Answer and working out are in the picture
The slope intercept form is y=-5x+37 (sorry, I didn't specify in the picture)

Answer: each of the students took 1/4 of an eraser home.

Step-by-step explanation:

On the last period our teacher had 1/2 of an eraser left. She gave it equally to 2 students. This means that the amount of eraser that each student takes home would be

(1/2)/2 = 1/2 × 1/2 = 1/4 of an eraser. Converting to decimal, it becomes 0.25 of an eraser.

Answer:

So, exist 18564 different possibilities.

Step-by-step explanation:

We know that the eighteen passengers get on an airport shuttle at the airport. The shuttle has a route that includes six hotels, and passengers get off the shuttle at their hotel.

We calcuate how many different possibilities exist that eighteen passengers can choose six hotels. We get:

$C_6^{18}=\frac{18!}{6!(18-6)!}=18564$
