What is the slope of the line passing through the given points 4,2 and -2,1

Mathematics

solniwko [45]3 years ago

Answer:

Alright, here is the formula.

m = (y2 -- y1) / (x2 -- x1)

So, now we have to take the points and replace them with the variables.

m = (1 - 2) / (-2 - 4)

Great! So now, we have to solve.

1 - 2 = -1

-2 - 4 = -6

So now, it would be:

-1/6

That is the slope! Hope this helps! :)

At 5:00 a.M., a parking lot had 16 cars already parked in it. Throughout the course of the day, 48 more cars entered and parked
Alekssandra [29.7K]

Answer:

The situation is that; the parking lot has 64 cars at the end of the day

<em></em>

Step-by-step explanation:

Given

Initial Number of cars = 16

Additional Cars = 48

Required

Determine the situation for the day

From the question, we understand that no car left the park;

This implies that

Number\ of\ cars = Initial\ Cars + Additional\ Cars

Number\ of\ cars = 16 + 48

Number\ of\ cars = 64

<em>So, the situation is that; the parking lot has 64 cars at the end of the day</em>

Use the information given to enter an equation in standard form.
Marysya12 [62]

Answer:

The equation in the standard form of the line through the given points is;

y = 3x - 17

Step-by-step explanation:

We start by getting the slope of the line;

m = (y2-y1)/(x2-x1)

m = (7-10)/(8-9) = -3/-1 = 3

The stands equation form is;

y = mx + b

m is slope, b is the y-intercept

so we have

y = 3x + b

To get b, we substitute the coordinates of any of the points

10 = 3(9) + b

10 = 27 + b

b = 10-27

b = -17

So the equation is;

y = 3x - 17

you rent a moving van. you have to pay a flat fee of $99 plus 50 cents per mile. You drive 120 miles. How much does it cost to d
Anna71 [15]

Answer:

Step-by-step explanation:

okey first you have to make the equation:

99+X0.5= ?

You express the 50cents like 0.5 because they are half a dollar

X signifies the you drove so X=120

99+120(0.5)

120 X 0.5= 60

99+60=150 You have to pay 150 dollars

This only works if your talking about dollars.

Hope this helped :)
