What is the equation of a line perpendicular to the line y = -1/5 x + 3 and going through the point (4,-1). Please write your answer in point slope form.

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

twenty-six miles over two gallons because the proportion for the original 13 miles to one gallon would be written 13/1 and, doing the same thing to the top and bottom, i multiplied by 2 and got 26/2

idk what the heck he answer is, i’m just putting this here so i finish my account
