Find the slope of the line.
(-4,1) (1,-2)

-3/5

Step-by-step explanation:

To find the slope of a line, use the formula y2-y1/x2-x1.

y2 and y1 are two different y values, and x2 and x1 are the corresponding x values.

y2 = -2

y1 = 1

x2 = 1

x1 = -4

Plugging the values in, we get -2 - 1/1 - (-4).

Evaluating -2 - 1 and 1 - (-4), we get -3/5.

Therefore, the final answer is -3/5.

a^1=4,

a^2=7,

d=3.

a^n=103.

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

103=4+(n-1)3

103-4=(n-1)3

99/3=n-1

33=n-1

n=34.
