Answer:
See attachment below
Step-by-step explanation:
Consider the given system of equation
x + y = -7 ........(1)
4x + y = 19 ..........(2)
Consider the equation (1)
x + y = -7
We first find different values of x and y that satisfies (1),
1) x = 1 , y = -7-1 = -8
We get one point as (1,-8)
2) x= 2 , y = -7 -2 = -9
We get point as (2 ,-9)
3) x = 0 , y = -7
We get point as (0 ,-7)
Similarly, find different values of x and y that satisfies (2),
4x + y = 19
1) x = 2 , y = 19 - 8 = 11
We get point as (0,11)
2) x= 3 , y = 19 - 12 = 7
We get point as (3 , 7)
3) x= 4 , y = 19 - 16 = 3
We get point as (4 ,3)
Now , we plot these point on the graph paper, we obtained graph as, (as attached below)
