Slope is 3, and (1, 4) is on the line.

y = 3x + 1

Step-by-step explanation:

The equation of a line in slope - intercept form is

y = mx + c (m is the slope and c the y - intercept)

Here m = 3, thus

y = 3x + c ← is the partial equation of the line

To find c substitute (1, 4) into the partial equation

4 = 3 + c ⇒ c = 4 - 3 = 1

y = 3x + 1 ← equation of line
