Answer:
When y = 5; x = 2
Explanation:
What we have to do here is to first go to the point y = 5 on the y-axis
Now, the next thing is to trace this to the plot
The tracing will meet the plot at a point
At this point, we can now drop a line to the x-axis
By this, we can get that at y = 5; then x = 2
Now, we want to check the validity from the linear equation given
That would be;
y = -x + 7
y = -2 + 7
y = 5
This holds according to the linear equation given
