Answer:
The slope of a line that is perpendicular to the given line is 
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:

Where "m" is the slope of the line and "b" is the y-intercept.
Solve for "y" from the equation of the line
:

You can observe that the slope of this line is:

By definition, the slopes of perpendicular lines are negative reciprocal, then, the slope of a line that is perpendicular to the give line, is

Answer:
well..the only equation is thats wrote right is(D)
Step-by-step explanation:
i wasnt sure if that was the correct answer and the way to know is by using i personally think which is desmos graphing calculator you can type in your equation and it graphs the line for you
I think it’s the first option
I'm not so good but I think thatmeans r is a different number and its half of 14 so figure out an equation
