Consider the line 7x+9y=5 what is the slope of a line parallel to this line?
what is the slope of a line perpendicular to this line?

The slope of a line parallel to this line will be: -7/9

The slope of the perpendicular line will be:

Step-by-step explanation:

We know the slope-intercept form

Here,

Given the equation

simplifying to write in the lope-intercept form

Thus, the slope of the line is: -7/9

The slope of a line parallel to the line:

We have already determined that the slope of the line is: -7/9

Thus, the slope of a line parallel to this line will be: -7/9

The slope of a line perpendicular to the line:

We have already determined that the slope of the line is: -7/9

As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line.

Thus,  the slope of the perpendicular line will be:

b. x + 1
