This is the one and i know its probably super easy but i dont know Which of these equations has a y-intercept of 3?

y = 3x

y = x + 3

y + 3 = x

y = x - 3

M the table below represents a linear function f(x) and the equation represents a function g(x): x f(x)−1 −50 −11 3g(x)g(x) = 2x − 7part a: write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x). (6 points)part b: which function has a greater y-intercept? justify your answer. (4 points)
