How do i find the slope if the y-intercept is 2

answer:

step-by-step explanation:

to find the y intercept using the equation of the line, plug in 0 for the x variable and solve for y. if the equation is written in the slope-intercept form, plug in the slope and the x and y coordinates for a point on the line to solve for y.

answer:

step-by-step explanation:

the slope-intercepts form is y=mx+b, where m is the slope and b is the y=intercepts

y=mx+b

find the values of m and b using the form y=mx+b

m=0

b=2

Function representing the sequence will be f(n) = (23 - 3n)

Step-by-step explanation:

The first five terms of an arithmetic sequence are as 20, 17, 14, 11, 8....

Let n represents the number of term and f(n) the the term in the sequence.

Then we have to find the function that represents the sequence.

As we know explicit formula of an arithmetic sequence is given by

Or the function representing the sequence will be

f(n) = a + (n-1)d

where a represents first term of the sequence a = 20

and common difference d = 17-20 = (-3).

Now the function which represents this sequence will be

f(n) = 20 + (n-1)(-3) = 20 - 3n + 3 = 23 - 3n
