Problema Solution
Indicate the equation of the line through (2, -4) and having slope of 3/5.
Answer provided by our tutors
let
m = 3/5 is the slope
(x1, y1) = (2, -4) is a point on the line
we will use the point - slope formula:
y - y1 = m (x - x1)
plug the values x1 = 2, y1 = -4, m = 3/5 into the last equation:
y - (-4) = (3/5)(x - 2)
by simplifying we find the equation of the line:
y = (3/5)x - (26/5)
