A line with a slope of 3/8 that passes through (0,-8)
ziro4ka [17]

Answer:

y = 3/8 - 8

Step-by-step explanation:

A line written in slope-intercept form is [ y = mx + b ] where m = slope and b = y-intercept

We are given the slope of 3/8

We are also given the point (0, -8) which is also the y-intercept.

y = 3/8 - 8

Best of Luck!

The recursive rule for a sequence is shown.
aleksandr82 [10.1K]
Given that the recursive formula is:
an=an-1+7
first term is
a1=17
the second term will be:
a2=a(2-1)+7
a2=a1+7
a2=17+7
a2=24
To evaluate for the explicit formula we use the formula:
an=a+d(n-1)
where
a=first term
d=common difference
from the calculations above:
d=24-17=7
thus the explicit formula will be:
an=17+7(n-1)
an=17+7n-7
an=7n+17-7
an=7n+10

Answer: B] an=7n+10
