Given:
[tex]y=7-4x[/tex]The equation represents a line written in slope-intercept form y= mx + b
Compare the given equation with the form
So, the slope = m = -4
And the y-intercept = b = 7
We will answer the following questions:
a) What is the slope of a line parallel to this line?
The parallel lines have the same slope
So, the slope of a parallel line = -4
b) What is the slope of a line perpendicular to this line?
the product of the slopes of the perpendicular lines = -1
So, the slope of a perpendicular line = 1/4
