A line contains the point (4, 2) and has a slope of −3.
Naya [18.7K]

Answer: the equation is y = - 3x + 14

Step-by-step explanation:

The equation of a straight line can be represented in the slope intercept form as

y = mx + c

Where

c represents the y intercept

m represents the slope of the straight line.

The slope of the given line is - 3 and it contains the point (4, 2)

To determine the y intercept, we would substitute m = - 3, x = 4 and

y = 2 into y = mx + c. It becomes

2 = - 3 × 4 + c

2 = - 12 + c

c = 12 + 2

c = 14

The equation becomes

y = - 3x + 14

Jonesville and smithville each have a population of size 2600 at time t = ​0, where t is measured in years. Suppose jonesville​'
ehidna [41]

Answer: B. Jonesville is growing linearly and Smithville is growing exponentially.

Step-by-step explanation:

Linear growth :

  • Population grow by a constant amount after each time period.
  • The rate of change of dependent variable with respect to independent variable is a constant.
  • It is represented by line on graph.
  • Equation for linear growth : y=mx+c , c = initial value and m is the rate of change of y with respect to x.

Exponential growth :

  • Population grow by a constant ratio .
  • It is represented by a curve on graph.
  • Equation for exponential growth : y=a(1+r)^x , a = initial value and r is  rate of growth ( in decimal ) and x is time period.

Given : Jonesville​'s population grows by 170 people per year.

i.e .Population grow by a constant amount per year.

⇒ Jonesville is growing linearly.

The population of smithville grows by 7​% per year.

i.e. Population grow by a constant ratio.

⇒Smithville is growing exponentially.

Hence, the true statement is "B. Jonesville is growing linearly and Smithville is growing exponentially."
