Determine the ordered pair that satisfies the equation, -5x + 3y = 7.
a) (2 , -1)
b) (-5 , 3)
c) (7 , 14)
d) (-2 ,−135)

C) (7 , 14)

Step-by-step explanation:

Substitute each ordered pair into the equation

-5x + 3y = 7.

A) (2 , -1)

-5(2) +3(1) = -10 +3 = -7  this does not equal 7  so not true

B) (-5 , 3)

-5(-5) +3(3) = 25 +9 = 34  this does not equal 7 so not true

C) (7 , 14)

-5(7) + 3(14) = -35 + 42 = 7  this equals 7 so true

D) (-2 ,−135)

-5(-2) + 3(-135) =10+405 =415  this does not equal 7 so not true

step-by-step explanation:

use that smart brain

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
