Answer:
y=-2x-7
Step-by-step explanation:
lines are typically written in y=mx+b form, where m is the slope and b is the y intercept
we are given the line y=1/2x-4
perpendicular lines are negative and reciprocal; if the slopes are multiplied together, the result is -1
so to find the slope of the new line, use this formula:
1/2m=-1
multiply by 2
m=-2
so the slope is -2
here's the equation so far, written in y=mx+b form
y=-2x+b
we need to find b
because the line passes through the point (-4,1), we can use it to solve for b
substiute -4 as x and 1 as y
1=-2(-4)+b
1=8+b
-7=b
so b is -7
therefore the line is:
y=-2x-7

Answer:
10/12
15/16
13/16
Step-by-step explanation:
each time you divide each of these they are over .5 or 50%
Answer:
The second option
Step-by-step explanation:
4x - 2 > 6x + 8
add 2 to both sides
4x - 2 + 2 > 6x + 8 + 2
2 cancel -2 and it remains
4x > 6x + 10
Now, subtract 6x from both sides
4x -6x > 6x -6x + 10
it remains
-2x > 10
divide via by -2
x > 10/-2
x < -5
When you multiply or divide by a negative, the inequality sign changes
