Answer:
A. y = 3x + 1
Explanation:
Find slope:
[tex]\sf slope: \dfrac{y_2 - y_1}{x_2- x_1} = \dfrac{\triangle y}{\triangle x} \ \ where \ (x_1 , \ y_1), ( x_2 , \ y_2) \ are \ points[/tex]
Take two points: (0, 1), (1, 4)
[tex]\sf \rightarrow slope \ (m) : \dfrac{4-1}{1- 0 } = 3[/tex]
Equation:
[tex]\sf y - y_1 = m(x - x_1)[/tex]
[tex]\sf y - 1 = 3(x - 0)[/tex]
[tex]\sf y = 3x + 1[/tex]
