Answer:
Step-by-step explanation:
1) y = 3x + 1
When x = -1 , y = 3*(-1) + 1
= -3 + 1
y = -2
(-1 , -2)
When x = 0 , y = 3*0 + 1
y = 1
(0 , 1)
When x = +1 , y = 3*1 + 1
= 3 + 1
y = 4
(1 , 4 )
Plot these points in the graph and join the points.
2) y = 2x -1
When x = -1 , y = 2*(-1) - 1
= - 2 - 1
y = -3
(-1 , -3)
When x = 0, y = 2*0 - 1
y = -1
(0 , -1)
When x = +1 , y = 2*1 -1
= 2 - 1
y = 1
(1 , 1)
Here, A.P. is 3x-1, 4x, 5x+1, 4
i) Common difference (d)
(5x-1) - 4x = x - 1
It would be same as 4 - (5x-1) = 4-5x+1 = 5-5x
Now, x - 1 = 5 - 5x
5x + x = 5 + 1
6x = 6
x = 6/6
x = 1
So, Common difference would be 1
ii) Eight term will be: a + (n-1)d = 2 + (8-1)2 = 2+7(2) = 2+14 = 16
So, eight term would be 16
Hope this helps!
