Solution:
The Ordered pair of the function is
x : 0 1 2 3 4 5
y: 13 21 29 37 45 53
(a)
Slope between two points are same.So,the function Represented in terms of ordered pairs Linear.
(b) As, you can each Successor of x values is obtained by adding 1 to it's Predecessor.
and , each Successor of y values is obtained by adding 8 to it's Predecessor.
(c) Taking any two ordered pairs , (0,13) and (1,21) we can find an equation of line passing through these 5 points (2,29),(3,37),(4,45),(5,53)
Equation of line passing through passing through two points is given by
=
=
→ y -13 = 8 x
→ y = 8 x + 13
So, Y intercept = 13
