Answer:
8.
Denote the equation : y = ax + b
Use the first 2 values of x and y in table:
3a + b = 21
5a + b = 35
Subtract the 2 equations:
=> 2a = 14 => a = 7 => b = 21 - 3 x 7 = 0
=> The solution is y = 7x
9.
Denote the equation : y = ax + b
Use the first 2 values of x and y in table:
5a + b = 17
10a + b = 22
Subtract the 2 equations:
=> 5a = 5 => a = 1 => b = 17 - 5 x 1 = 17 - 5 = 12
=> The solution is y = x + 12
Hope this helps!

Step-by-stepapex answer to the left of 9.9 and to the right of 9.3 explanation:
Answer:
uhh the slope formula is
To calculate the slope of a line you need only two points from that line, (x1, y1) and (x2, y2). The equation used to calculate the slope from two points is: On a graph, this can be represented as: There are three steps in calculating the slope of a straight line when you are not given its equation
Answer:
Option D) 
is correct
Therefore 
Step-by-step explanation:
Given polynomial is 
To factorise the given polynomial by taking out the common terms of the given polynomial :
( here 2y is GCF common term so taking outside the terms of the polynomial )
( now taking (-) outside )
Therefore
Option D) is correct
