-6.9x - 7.8y = 71.76
to find the y int, sub in 0 for x and solve for y
-6.9(0) - 7.8y = 71.76
-7.8y = 71.76
y = 71.76/-7.8
y = -9.2...so the y int is (0,-9.2)
to find the x int, sub in 0 for y and solve for x
-6.9x - 7.8y = 71.76
-6.9x - 7.8(0) = 71.76
-6.9x = 71.76
x = 71.76 / -6.9
x = -10.4....so ur x int is (10.4,0)
Answer: 8
Step-by-step explanation: That digit above the 2 is a exponent. It represents the number of times 2 is multiplying itself. This is simply 2x2x2. 2x2x2=4x2=8
