y = 3x + 1
y = - 6x + 10
A. (1, 2)
B. (4,1)
C. (1.4)
D. No Solution

Answer 1

D. (1,4)

Explanation:

y = 3x + 1

y = - 6x + 10

Substitution:

3x + 1 = -6x + 10

3x + 6x = 10 - 1

9x = 9

x = 9/9 = 1

y = 3(1) + 1

y = 3 + 1

y = 4

Answer 2

Answer: C

Explanation:

(4) = 3(1) + 1

4 = 3 + 1

4=4

TRUE

(4) = -6(1) + 10

4= -6 + 10

4= 4

TRUE
