What is the slope of (-7, 0), (-7, -6)?
Bess [88]

Answer:

A line passes (-7, 0), (-7, -6).

These two passed points have same x-component (x = -7).

=> This is the line which has equation: x = -7.

This is a vertical line (parallel with y axis) and the slope is undefined.

Hope this helps!

:)

Find the missing lengths. Plz help math is not my subject
ruslelena [56]

For the figure on the left, the answers are a = 8 and b = 4

This is a 30-60-90 triangle. The short leg is always opposite the smallest angle (30 degrees). The rule is the smallest side is opposite the smallest angle. Similarly, the largest side is opposite the largest angle. In a right triangle the largest side is always opposite the 90 degree angle. This side is the hypotenuse.

Recall that the longer leg is sqrt(3) times the short leg. The notation "sqrt" is shorthand for "square root".

So long leg = (short leg)*sqrt(3) which means b = 4 must be the case to end up with long leg = 4*sqrt(3)

The hypotenuse is twice that of the short leg, so a = 2*b = 2*4 = 8

=======================================

For the figure on the right, the answers are x = 2*sqrt(3) and y = 2

The short leg is y, which is opposite the 30 degree angle (this is another 30-60-90 triangle). So y is half of the hypotenuse 4. That explains how y = 2.

The long leg x is equal to sqrt(3) times the short leg, so

(long leg) = (short leg)*sqrt(3)

x = y*sqrt(3)

x = 2*sqrt(3)
