(x₁, y₁) = (1, 4)
(x₂, y₂) = (3, 2)
m = slope
= rise / run
= (change in y) / (change in x)
= (y₂  y₁) / (x₂  x₁)
= (2  4) / (3  1)
= 6 / 2
= 3
Use that slope and either of the given points in the pointslope form of an equation for a line. I'll use point (x₁, y₁) = (1, 4) :
y  y₁ = m(x  x₁)
y  4 = 3(x  1)
y  4 = 3x + 3
y = 3x + 7
