Answer:
1) a1 = -5, a(n) = a(n-1) + 2
Step-by-step explanation:
The explicit formula for an arithmetic sequence can be written ...
an = a1 +d(n -1)
The corresponding recursive formula is ...
a(1) = a1, a(n) = a(n -1) +d
__
Comparing the above explicit formula to the one you're given, you see that ...
a1 = -5, d = 2
Using these values in the recursive formula gives you ...
a(1) = -5, a(n) = a(n-1) +2

Answer:
y = 38x
Step-by-step explanation:
The constant of proportionality (k) is the value of y when x=1. The table shows that to be 38. Then the equation is ...
y = kx
y = 38x
Answer:
The y intercepts is -2
y = 1x-2
Step-by-step explanation:
The y intercept is where it crosses the y axis
The y intercepts is -2
We need to determine the slope, by using to points on the line
(0,-2) and (2,0)
m = (y2-y1)/(x2-x1)
= (0 --2)/(2-0)
= (0+2)/(2-0)
= 2/2
= 1
The equation for the line is
y = mx+b where m is the slope and b is the y intercept
y = 1x-2
