The graph of the transformed linear equation is in the image at the end.
How to find the translation?
The linear function in the graph has an y-intercept at:
y = -2
So we can write:
y = a*x - 2
To find the value of a, we can see that this line also passes through (1, 2), then:
2 = a*1 - 2
2 + 2 = a
4 = a
The equation is:
y = 4x - 2
If we add 6, we will get:
y = 4x - 2 + 6
y = 4x + 4
The graph of this line is in the image at the end.
