Answer:
Step-by-step explanation:
The point-slope form of equation of a line is:
y - y₀ = m(x - x₀)
where (x₀, y₀) is the point which the line passes through and m is the slope of the line
The product of slopes of two perpendicular lines is -1
so if given lines slope is 10 them:
10·m = -1
m = -0.1
(6, -4) ⇒ x₀ = 6, y₀ = -4
Therefore:
y - (-4) = -0.1(x - 6)
y = -0.1x + 0.6 + (-4)
y = -0.1x - 3.4
