I really need help on this question
1 answer:
Answer:
B
Step-by-step explanation:
y = is the equation of a horizontal line, parallel to the x- axis.
A line perpendicular to it will be a vertical line parallel to the y- axis with equation
x = c
where c is the value of the x- coordinates the line passes through.
The line passes through (- 6, - 9) with x- coordinate - 6, thus
x = - 6 ← is the equation of the perpendicular line

For this case we must find the solution of the following system of equations:
If we multiply the first equation by -2 we have the following equivalent system:
If we add the equations we have:
Thus, the system has infinite solutions.
