Find the equation of the linear function represented by the table below in slope-intercept form. x y
1 -5
2 -9
3 -13
4 -17

d -7

Step-by-step explanation:

The sum of an arithmetic sequence Sn whose first and last terms are known may be expressed as

Sn = n/2(a + l)

where a and l are the first and last terms of the arithmetic sequence with n number of terms

Thus for the  given sequence, the sum Sn is

S₇ = 7/2 (-10 + 8)

Since there are 7 terms in the sequence

= 3.5 * -2

= -7
