Answer:
y - 10 = 5(x - 15)
Explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (15, 10) and (x₂, y₂ ) = (16, 15)
m =
=
= 5
Using (a, b) = (15, 10), then
y - 10 = 5(x - 15)
