The answer is B.
Function means every x corresponds to one unique y value. ACD all have duplicates correspondence.
Answer: 8x - 1
Step-by-step explanation:
Answer:
y = 4x + 1
Step-by-step explanation:
y = mx + b
The line goes thru (0, 1) and (1, 5)
The slope = m = (5 - 1)/ 1 - 0) = 4/1 = 4
The y-intercept is (0, 1), so b = 1
y = 4x + 1 is the equation of the line
I hope this helps, wrote out the explanation cause its better on paper.
