Answer:
y = -x + 10
Step-by-step explanation:
To find the equation of a line that passes through the point (8,6) and perpendicular to the equation 2x - y = 4, we will follow the steps below:
first write the equation 2x - y = 4 in a standard form
we will find the slope of our equation using this equation
2x - y = 4
y = 2x -4
comparing the above with
y = mx + c
m = 2
= -1 ( slope of perpendicular equations)
2 = -1
= -1/2
our slope m = -1/2
We can now go ahead and form our equation
=8
=6
y- = m (x-
)
y-6 = -(x-8)
y-6 = -x + 4
y= -x+4+6
y = -x + 10
If you need to write a number as a decimal, it means that you need to write is a an x divided by a power of 10.
you can use this formula:
now let's multiply both sides by 10:
and simplyfy:
(by dividing the first fraction's elements by 5)
change improper fraction into a mixed number
and 1 over 3 is 0.33333...
so the answer is 1.333333 - we can also write it as 1.(3)
