What happens to a line when the y-intercept is changed? check all that apply. a. as the y-intercept decreases, the graph of the line shifts left. b. as the y-intercept increases, the graph of the line gets steeper. c. as the y-intercept decreases, the graph of the line shifts down. d. as the y-intercept increases, the graph of the line shifts up. e. as the y-intercept increases, the graph of the line shifts right.

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for

you have to put the graph on here with the question

step-by-step explanation:

a = (-2, 0)

b= (-4, 0)

c = (-5,2)

d = (-1,2)
