Answer:

In the year 2010, the population of the city was 175,000

Step-by-step explanation:

If we rewrote this as a linear expression in standard form (it is linear, btw), it would look like this:

P(t)=\frac{11}{2}t+175

The rate of change, the slope of this line, is 11/2.  If the year 2010 is our time zero (in other words, we start the clock at that year), then 0 time has gone by in the year 2010.  In the year 2011, t = 1 (one year goes by from 2010 to 2011); in the year 2012, t = 2 (two years have gone by from 2010 to 2012), etc.  If we plug in a 0 for t we get that y = 175,000.  That is our y-intercept, which also serves to give us the starting amount of something time-related when NO time has gone by.

Find the equation of the line shown.
den301095 [7]

Answer:

y = (-1/4)*x+2

Step-by-step explanation:

The equation is written this way : y= mx+c

  • m is the slope and c is a constant
  • m = (f(4)-f(-4))/(4-(-4))= (1-3)/8 = -1/4
  • y = (-1/4)*x + c
  • replace x and y by the coordinates of a point to get c
  • 1 = -1/4*4+c
  • 1= -1+c
  • c= 2

y = -1/4*x+2
