The value of x is either +7 or -8
Answer:
Step-by-step explanation:
2x + 3y = 4
When y = 34
2x + 3(34) = 4
2x + 102 = 4
2x = 4 - 102
2x = - 98
x = -98/2
x = - 49
Answer:
B. y = 2x - 9
Step-by-step explanation:
All of the answer choices has a slope of 2, but B is the only answer choice that has (4,-1) on its line.
You can tell by plugging the point into the equation and seeing if the result is true.
y = 2x - 9
-1 = 2(4) - 9
-1 = 8 - 9
-1 = -1
