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)

Step-by-step explanation:
Sum of two sides always greater than the third side
If c is the smallest number, then
5 + c > 7
c > 2
If c is the largest number, then
5+7>c
12>c
Adding c>2 and 12>c, you get 12>c>2 for the answer
