point slope form of a line

y-y1 = m(x-x1)

y-7 = -2 (x-1)

if you want it in slope intercept form

y-7 = -2x +2

add 7 to each side

y = -2x +9

what is the slope of the line that passes through the points (-4,-4) and (-4,-9)? Write your answer in simplest form
Aneli [31]

Answer:

undefined

Step-by-step explanation:

We can find the slope of a line using two points by

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

   = (-9- -4)/(-4 -  -4)

    = (-9+4)/(-4+4)

   = -5/0

When we divide by zero, our solutions is undefined

The slope is undefined

Answer:

In this equation, let "x" equal the rate at which the tub will be filled. The tub holds 32 gallons, which will be one half of the equation. The tub already contains 12 gallons, so this will be half of the other side of the equation. The rate is "x" gallons per minute, and the time it required was 5 minutes, so this would be "5x". Placing all these parts together gives an equation of (32 = 5x + 12) gallons per minute dispensed.

Answer:

1.  f(0) =  501170

2.  decreasing

3.  2% decrease

4. 302438

Step-by-step explanation:

In 1995 x=0

f(x) = 501170(0.98)^0

f(0) =  501170

The population is decreasing since we are multiplying by .98 ^x

.98 is less than 1 so it is getting smaller each time.

1 -.98 = .02

It is decreasing by 2 % each year

2020-1995  =25 years

f(25) = 501170(0.98)^25

        =302438.41862

Rounding to the nearest whole number

          302438
