Answer:
2x + y = 20
Step-by-step explanation:
gradient = -2
x = 6, y = 8
y - 8 = -2(x - 6)
y - 8 = -2x + 12
2x + y = 12 + 8
2x + y = 20
Answer:
a
the first answer
Step-by-step explanation:
By intuition, the function of y with respect to x will be:
y = 4x
You can prove this by substitute in each pair of values of x and y
So the constant of relationship is 4
So your seeing what the difference is between them
