Chin was shown the graph of a line that contained point 1 comma 7 He wrote f of x is equal to 4 x plus 3 to correctly represent the line. Which of these equations could represent the same line?

The equation f(x) = 4x + 3 has slope 4, and it passes through (1, 7) because 4(1) + 3 = 7. Using point-slope form, y − y₁ = m(x − x₁), gives y − 7 = 4(x − 1). That is choice A.
