Lindsay's debt is greater. Which is more? $20 or $15? I don't know how to express debt... Sorry.
The gradient of the perpendicular line would be the negative reciprocal of the original line. Therefore the gradient of the perpendicular line would be -2/5x.
Since we know y=mx+c, ∴y=-2/5x+c. Sub in the x and y values of the given point and we get that c=26/5.
The perpendicular equation would be y=-2/5x+26/5.
I hope I got this right.
The answer to you’re question is 5 1/2 multiplied by 5 1/3. I submitted a photo showing how to put the answer.
