Answer:
y = -2x + 5
Step-by-step explanation:
Given:
Passes through point (1, 3)
Perpendicular to x – 2y = -8
Solve:
x – 2y = -8
y = 1/2x + 4
The slope is m = 1/2
The slope of the perpendicular line is the inverse of the slope of the original equation.
The slope of the inverse equation is m = -2.
Making an inverse equation of y = -2x + a
Find a:
Use point, (1, 3) where (x, y):
3 = (-2)*(1) + a
a = 5
y = -2x + 5
Answer:
27
I'm not sure how to explain it
Given:
A line has a slope = -9
The line passing through the point (-4 , -2)
the general form of the equation of the line in point - slope form is :

Where: m is the slope, and ( h,k) is the point
So,

So, the equation of the line will be:

The answer is option C. y + 2 = -9 ( x + 4 )
There are 2000 pounds in one ton, so to find the amount of pounds in a set amount of tons, all we need to do is multiply the amount of tons by the amount of pounds in one ton.
12 * 2000 = 24000
There are 24,000 lbs in 12 tons.
Hope that helped! =)
