Do you need to ask this question ???

By the way, here is the solution

Formula: equation of line passing through (a, b) and (c,d) is y - b = m (x - a), m is slope

(1) find the slope of line
m = \frac{7 - 5}{3 - 1} \\  \\ m =  \frac{2}{2} \\  \\ m = 1

(2) find the equation
y - 5 = 1 (x - 1)
⇒ y - 5 = x - 1
⇒ y = x + 4

Answer
y = x + 4
