Answer:
y =
x + 9
Explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m =
with (x₁, y₁ ) = (0, 9) and (x₂, y₂ ) = (6, 10) ← 2 points on the line
m =
=
the line crosses the y- axis at (0, 9 ) ⇒ c = 9
y =
x + 9 ← equation of line
