What is the solution of the system? use substitution. y = −3xx + y = −4a. (-2,-6)b. (2, −6)c. (2, 6)d. (−2, 6)

x=2 ,y=-6

B (2,-6)

Step-by-step explanation:

y = -3x

x+y = -4

Substitute -3x for y in the second equation

x+y = -4

x+ (-3x) = -4

Combine like terms

-2x = -4

Divide by -2 on each side

-2x/-2 = -4/-2

x = 2

Now we still need to find y

y = -3x

Substitute x=2

y = -3(2)

y = -6

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

1 1/5
