An equation of line with slope m = 5 and which goes through the point (8, -9) is y = 5x - 49
In this question, we have been given a slope of the line and a point (8, -9)
We need to find an equation of the line with slope m = 5 and which goes through the point (8, -9)
Let (x1, y1) = (8, -9)
Using the slope-point form of the line,
y - y1 = m(x - x1)
y - (-9) = 5(x - 8)
y + 9= 5x - 40
y = 5x - 40 - 9
y = 5x - 49
Therefore, an equation of line with slope m = 5 and which goes through the point (8, -9) is y = 5x - 49

Answer:
x = 3
Step-by-step explanation:
The recursive formula for this sequence is
= -7;
=
+ 10
Step-by-step explanation:
The recursive formula of the arithmetic sequence is:
= first term;
=
+ d
is the first term in the sequence
is the nth term in the sequence
the term before the nth term - n is the term number
- d is the common difference
∵ The sequence is -7 , 3 , 13 , 23 , 33 , 43 , ........
∵ 3 - (-7) = 3 + 7 = 10
∵ 13 - 3 = 10
∵ 23 - 13 = 10
- There is a constant difference 10 between the consecutive terms
∴ The sequence is an arithmetic sequence
∵ The first term is -7
∴
= 7
∵ The common difference is 10
∴ d = 10
- Substitute in the formula above
by -7 and d by 10
∴
= -7;
=
+ 10
To check the formula find the second term
∵ n = 2
∴
= -7;
=
+ 10
∴
=
+ 10
∵
= -7
∴
= -7 + 10 = 3 which is right
The recursive formula for this sequence is
= -7;
=
+ 10
