find an equation of the line that is perpendicular to the line 4x - 5y = 4 and passes through the point (7, -3)
The given equation of line is 4x-5y=4 …. (1)
To find the equation of line which is perpendicular to 4x-5y=4 and passes through the point (7, -3), first find the slope of line 4x-5y=4.
Reduce the equation (1) into slope-intercept form.
On comparing Equation (1) and (2) m=4/5 and c=-4/5.
Therefore, slope of equation (1) is 4/5.
Since slope of perpendicular lines are negat...
