The slope of line f which is perpendicular to the line e is 5/9
What is an equation?
An equation is an expression that shows the relationship between two or more numbers and variables.
An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.
Line e passes through points (1, 12) and (6, 3), the equation is:
y - 12 = [(3 - 12)/(6 - 1)](x - 1)
y = -(9/5)x + 13.8
Two lines are perpendicular if the product of their slope is -1.
Since line f is perpendicular to e, hence:
Slope of line f = 5/9
The slope of line f which is perpendicular to the line e is 5/9
