Answer:

aₙ = a₁ + (n-1).d

103

107

Step-by-step explanation:

This is an arithmetic sequence because the difference (d) between 2 successive numbers is constant.

d = 91 - 87 = 95 - 91 = 99 - 95 = 4

If the first term is a₁, we can find the n term using the following expression.

aₙ = a₁ + (n-1).d

Here, we want to find the fifth and sixth elements.

a₅ = 87 + (5-1).4 = 103

a₆ = 87 + (6-1).4 = 107

What is the slope of the line passing through the points (-1,-7) and (-9,-2)?
nalin [4]

Answer: m = -5/8

Step-by-step explanation:

The general equation for slope is rise over run, also known as:

m=(y2-y1)/(x2-x1)

From the points (x, y), we can get all the variables we need.

(-1, -7) gives us x1 = -1 and y1 = -7

(-9, -2) gives us x2 = -9 and y2 = -2

If we plug all the values in, we get:

m = (-2 - (-7))/(-9 - (-1))

m = (-2 + 7)/(-9 + 1) the negatives cancel

m = (5)/(-8)

m = -5/8
