Consider the line 9x - 7y=-8.

What is the slope of a line perpendicular to this line?

What is the slope of a line parallel to this line?

Slope of a perpendicular line:

Х

?

Slope of a parallel line:

Step-by-step explanation:

Before you can answer you have to solve the equation for y.

Y = 9/7 x+8/7

Parallel lines have the same slope so would also be 9/7

Perpendicular lines have opposite reciprocal slope so would be - 7/9
