Answer:
- 57
Step-by-step explanation:
The n th term of an arithmetic sequence is
= a + (n - 1)d
where a is the first term and d the common difference
Here a = 13 and d = - 2.5, thus
= 13 + (28 × - 2.5) = 13 - 70 = - 57
Slope = (y2 - y1)/(x2 - x1)
= (1 + 7)/(9 + 3)
= 8 / 12
= 2/3
answer
2/3
Y = 0.75x - 6
If the line is parallel then the gradient is the same
Substitute in the values x = 4 and y = 5
5 = 0.75x4 +c
5 = 1 + c
c = 4
The equation of the line:
Y = 0.75x + 4
