The product of 5 and a number x is ¼

a.5x=¼
b.x= 1/20
c.x=5/4
d.x/5=1/4
e.x+5=1/4
f.x=-19/4

The answer to your question is:                y = -R/P x  + R

Step-by-step explanation:

Data

x-intercept (P,0)

y-intercept (0,R)

Slope

             m = (y2 - y1) / (x2 - x1)

             m = (R - 0) / (0 - P)

             m = R / -P  = - R / P

Equation

            (y - y1) = m(x - x1)

            (y - R) = - R/P (x - 0)

             y - R =  - R/P x

             y = -R/P x  + R
