Find 2 "easy" points on the graph, and identify their coordinates.  One such point would be (-4,1) and another would be (4,2).

run = 8 (from -4 to +4)
rise = 2 (from 0 to 2)

              rise           2
slope = ------- = -------- = 1/4                   y-intercept is (0,1)
               run          8

equation of this line is   thus   y = mx + b, or   y = (1/4)x + 1  (answer)

PLEASE HELP ASAP
makkiz [27]

Answer:

5

Step-by-step explanation:

Since the difference in each term number is 5, we put 5 in the place of the star.

Formula for constant difference in a pattern: Tn= an+b

a is the difference while b is the number that comes before the 1st term. So, the equation to find the nth term is Tn=5n+4.

Hope this helps and please give a brainlist, thank you!
