y = kx ← k is the constant of proportionality
To find k use the point (1, 4), that is x = 1, y = 4
k = = = 4
Answer:the 2nd row, x=0, f(x)=2
Step-by-step explanation:
When x=0, the line touches the y-axis because the f(x) has a value. therefore when x=0, y=2
you'll understand better if you sketch it out
