It is reported that the grizzly bear population has increased by 140% since 1975.
there are now 600 grizzly bears living in the wild.
how many grizzly bears were there living in 1975?

  250

Step-by-step explanation:

If we let p represent the 1975 population, we have ...

  p + 140%×p = 600

  p(1 +1.40) = 600

  p = 600/2.4 = 250

There were 250 grizzly bears living in the wild in 1975.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
