Is the line y=7x+2 perpendicular to the y=-1/7x+12 explain.

The line y = 7x + 2 perpendicular to the .

Solution:

Equation of one line:

Slope of this line:

Equation of another line:

Slope of this line:

If two lines are perpendicular, then the product of their slope is -1.

Both 7's get canceled, we get

Therefore, product of slopes of the given lines are -1.

Hence, the line y = 7x + 2 perpendicular to the .
