What is the slope of a line perpendicular to a line whose equation is -4x - 2y + 18 =0 ?

Slope of a line perpendicular to a line whose equation is -4x - 2y + 18 = 0 is  

Given that the line equation is -4x - 2y + 18 = 0

We have to find the slope of line perpendicular to the above line equation

Let us first find the slope of given line

The slope intercept form of a line is given as:

y = mx + c

where "m" is the slope of line and "c" is the y - intercept

Given equation of line is:

-4x - 2y + 18 = 0

Let us rearrange the above equation into slope intercept form

2y = -4x + 18

y = -2x + 9

Comparing y = -2x + 9 with general slope intercept form y = mx + c, we get,

m = -2

Thus the slope of give line equation is -2

Now we have to find the slope of line which is perpendicular to given line having equation -4x - 2y + 18 = 0 and slope -2

Since the lines are perpendicular, product of slopes of both lines is equal to -1

Slope of line perpendicular to given line x slope of given line = -1

Slope of line perpendicular to given line x -2 = -1

Slope of line perpendicular to given line =

Thus slope of a line perpendicular to a line whose equation is -4x - 2y + 18 =0 is  

c is the answer

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
