The
y = 3/4x + 7 and 4x - 3y = 9

The
line y = 3/4x + 7 is in slope-intercept form, where the slope is 3/4.
To determine the slope of the second line 4x - 3y = 9, we can rearrange it into slope-intercept form:
4x - 3y = 9
-3y = -4x + 9
y = 4/3x - 3
The slope of the second line is 4/3.
Since the slopes of the two lines (3/4 and 4/3) are reciprocals of each other, the lines are perpendicular.
To determine the slope of the second line 4x - 3y = 9, we can rearrange it into slope-intercept form:
4x - 3y = 9
-3y = -4x + 9
y = 4/3x - 3
The slope of the second line is 4/3.
Since the slopes of the two lines (3/4 and 4/3) are reciprocals of each other, the lines are perpendicular.
