Answer:
perpendicular
Step-by-step explanation:
The first equation can be written in slope-intercept form as ...
y = -1/2x - 3
In this form, we see that the slopes of the two lines are -1/2 and 2, so the product of their slopes is -1. That means the lines are perpendicular.
Given:
Consider the number as <em>x</em>.
The objective is to represent algebraic expression for, 2 is subtracted from the square of a number.
Explanation:
Since the number is given as <em>x</em>, the square of the number can be represented as,
Now, subtract 2 from the above expression,
Hence, the required expression is x²-2.
