SOLUTION: find an equation for the line with the given properties. express the answer using the general form of the equation of a line. perpendicular to the line -4x+5y= -23; containing t

Question 975860: find an equation for the line with the given properties. express the answer using the general form of the equation of a line.
perpendicular to the line -4x+5y= -23; containing the point (-3,7)
I think it would be -5x+4y=-13 but I could be mistaken.
Answer by Boreal(15235) (Show Source): You can put this solution on YOUR website!
The first line is y=(4/5)x -(23/5)
The second line MUST have a slope of (-5/4)
point slope formula
y-7=(-5/4)(x+3)
y=(-5x/4)+3
graph below shows these two plus yours (in blue); green is the perpendicular line to the original.
