The best graph is option 1 represents the solutions to the pair of equations y = 4x + 2 and y = x + 5.
What is graph?
A graph is "pictorial representation or diagram that represents data or values in organized manner".
According to the question,
The pair of equations are y = 4x + 2 and y = x + 5.
4x+2 = x+5
3x = 5-2
3x = 3
x = 1
Substitute x = 1 in y = x+5
y = 1 + 5
y = 6.
Hence, the point at which pair of equation intersect is (1,6). Thus, the best graph is option 1 represents the solutions to the pair of equations y = 4x + 2 and y = x + 5.
