3. The linear equation passing through the intersection of two lines 3x-2y + 10 = 0 and 4x-3y + 2 = 0 and perpendicular to the line 2x-3y + 1 = 0

3. The linear equation passing through the intersection of two lines 3x-2y + 10 = 0 and 4x-3y + 2 = 0 and perpendicular to the line 2x-3y + 1 = 0

The obtained line is perpendicular to the line 2x-3y + 1 = 0, and the slopes of the two lines perpendicular to each other are negative reciprocal (except for the X and Y axes), so the slope of the obtained line is - 3 / 2. It is easy to obtain the intersection coordinates of the lines 3x-2y + 10 = 0 and 4x-3y + 2 = 0 (- 26, - 34), and the linear path 3x + 2Y + 146 = 0 by using the point oblique formula
