Answer:
Graph is attached below
Explanation:

To graph this linear function , we make a table
Assume some random number for x and find out y. Assume some positive and negative numbers for x
x y=-4x+7
-1 -4(-1)+7=11
0 -4(0)+7=7
1 -4(1)+7=3
The points we got are (-1,11) (0,7) (1, 3)
Plot all the points and join all the points by a line
The graph is attached below
