10)
A) x + 2 y = 1
C) x - 2y = 10
B) x-1= 2
D) x – 2y=

B)

Step-by-step explanation:

y-intercept = -2

slope = 1

in slope-intercept form the line would be:  y = x - 2

if we subtract 'x' from each side we get:

-x + y = -2

we don't want to leave 'x' as negative so we can multiply each term by -1 to get:

x - y = 2

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5
