a gradient of a line that is parallel and perpendicular to this line with this gradient of -2
Gradient is the slope
So slope of the line =-2
Slope of parallel line is equal to the slope of the line
So slope of parallel line = -2
Slope of perpendicular line is equal to negative reciprocal of slope of the line
We know slope of line = -2
Negative reciprocal = 
So , Slope of perpendicular line= 
Answer:Infinite solution
Step-by-step explanation:
For Inequalities

3y-6x>2
and 
3y-6x<1
The required Inequalities have no solution because they do not share the common region for a common solution
But if signs of both inequalities is changed then the system has infinite number of solution.

3y-6x<2
and 
3y-6x>1
Answer:
The answer is
<h2>3x - 10</h2>
Step-by-step explanation:
(5x - 3) - (2x + 7).
<u>Remove the brackets</u>
That's
5x - 3 - 2x - 7
<u>Group like terms and simplify</u>
That's
5x - 2x - 3 - 7
We have the final answer as
<h3>3x - 10</h3>
Hope this helps you
