Answer:

a

Step-by-step explanation:

Answer:

(2,1)

Step-by-step explanation:

y = -4x + 9  -------------->eq1

y = 3x - 5  --------------->eq2

consider eq 1 and put in eq2

-4x+9=3x-5

add -9 on both sides

-4x=3x-14

add -3x on both sides

-4x-3x=-14

-7x=-14

x=2

put in eq1

y=-4(2)+9

y=1

S.S=(2,1)
