Answer:
The other line is y= 8x - 7
Step-by-step explanation:
The given equation in two variable is
y= 8x ± 7
The two equations in two variables are:
Ax + By +C=0
P x + Q y +R=0
Now, the condition that these two equations has no solution is if;
A/P = B/Q ≠ P/R
Another condition is in terms of line , if the two lines have same slope.
For example, y= ax + b and , y = ax + p are two lines having same slope means they are parallel, that is they will never intersect.
If the line is , y = 8x + 7, the other line will be, y= 8x - 7
