gradient= (10,000- 20,000)/(5-0)= -2000 ...........calculated by taking extreme points of the line, i.e. (0,20000) & (5,10000)

notice that gradient of the line is negative

y-intercept= 20,000

equation of line: V= -2000y+ 2000

now put the value of y=7 to see the corresponding value

V = (-2000)7 + 20000 = 6000
