Answer:
y = 5x + 2
Step-by-step explanation:
slope intercept form is y = mx+ b
the y- intercept is 0,2 so 2 is your b.
for m you do rise over run aka y/x. for every 5 rise up the x runs one so your slope(m) = 5
so y=5x+2

The function defined by f(t)=12(1+0.03)t can be used to determine the population, in thousands, of a town t years since 1955. According to the function, what was the population of the town in 1955 and what was the percent increase in population from year to year?
Enter a number in each box to correctly complete the sentence.
Answers
The population of the town in 1955 was 12 thousand people, and the percent increase in population from year to year was 3%.
How to explain the population?A function assigns the value of each element of one set to the other specific element of another set. The function that gives the population of the town is given.
Since the year 1955 the value of t=0. Therefore, The population of the town in 1955 was 12 thousand. The percentage increase in population from year to year is 3%.
Therefore, the population of the town in 1955 was 12 thousand people, and the percent increase in population from year to year was 3%.

The mean age of a group of students is 16. John joins the group and the mean age changes to 18. How old is john ?
Answers
Answer:
John is 20 years old.
Step-by-step explanation:
Given the second mean is 18, it is equal to the first mean age plus John's unknown age. The sum is also divided by 2 because there are 2 values in the sum (1. John's age and 2. the mean, 16 yrs old).
Set up an equation: [tex]\frac{x+16}{2}=18[/tex]
multiply both sides by 2: [tex]x+16=36[/tex]

Find the equation of the line in slope-intercept form containing the two points: (−1,5) and )(4,−3) Leave equation in fractional form.
Answers
Answer:
y = 1.6x + 3.4
Step-by-step explanation:
We have to use the equation y = m x + c to find the equation of the line.
Here,
m ⇒ slope
c ⇒ y-intercept
First, let us find the slope.
For that, we can use the given two coordinates.
( -1 , 5 ) ⇒ ( x₁ , y₁ )
( 4 , -3 ) ⇒ ( x₂ , y₂ )
The formula to find the slope of a line is :
m = ( y₁ - y₂ ) ÷ ( x₁ - x₂ )
Let us solve now.
m = ( y₁ - y₂ ) ÷ ( x₁ - x₂ )
m = ( 5 - ( -3 ) ) ÷ ( -1 - 4 )
m = ( 5 + 3 ) ÷ -5
m = 8 ÷ -5
m = -1.6
Now let us find the y-intercept (c ) of the line.
For that, let us get one of the coordinates which are given in the question.
I'll get ( -1 , 5 ) from that.
( -1 , 5 ) ⇒ ( x , y )
Let us solve now.
y = mx + c
5 = -1.6 × -1 + c
5 = 1.6 + c
5 - 1.6 = c
3.4 = c
Therefore,
m ⇒ -1.6
c ⇒ 3.4
So, the equation of the line is :
y = mx + c
y = 1.6x + 3.4
