Answer:
-1/2
Step-by-step explanation:
Rearranging this equation to slope-intercept form, we see the slope (x-coefficient) is 2:
2x = 7 + y . . . . . add y
y = 2x -7 . . . . . . subtract 7
The slope of the perpendicular line is the opposite of the reciprocal of this:
-1/2 = slope of perpendicular

=======================================================
Explanation:
The plane P can be thought of a perfectly flat ground. Now imagine a flag pole which represents line GH. If AB is drawn in chalk on the pavement, and this line AB intersects the base of the flagpole, then we've made AB and GH intersect. However, this example shows that GH is <u>not</u> on the plane P.
Is it possible to have GH be in the the plane? Yes. We could easily draw another chalk line on the ground to have it intersect AB somewhere. But as the previous paragraph says, it's also possible that GH is not in the plane.
Therefore, the statement is sometimes true
Answer:
√2
Step-by-step explanation:
As a fraction, 2 is 2/1
Oh no, there is always an odd exponent. So it could not have been made by squaring a rational number! This means that the value that was squared to make 2 (ie the square root of 2) cannot be a rational number. In other words, the square root of 2 is irrational.
