Check out the attached image for the full two-column proof. Feel free to ask any questions you have. The proof hopefully is self-explanatory. The only thing I would like to make a note on is a "linear pair" is where you have two angles that are adjacent (touching each other) and they form a straight angle. Those properties apply to angle 1 and angle 3, which is why they are a linear pair. So that points to them being supplementary (they add to 180 degrees).

What is the slope of the line that contains the points (-12, -15) and (-6, -23)?
yuradex [85]
Slope = \frac{y2-y1}{x2-x1}
-------------
-23 - (-15) = -8
-6 - (-12) = 6
-------------------
-8/6 or -4/3 is your answer

Find the slope of the line through the points (4, 4) and (-1, 5).
Phoenix [80]
<span>We write pattern linear function
f(x) = ax + b

</span><span>Both points must be in one straight line so they can be used to lay the system of equations .
Points A=(4,4), B = (-1,5)
                x  y            x  y

</span>\left \{ {{f(x)=ax + b  (Point A)} \atop {f(x) = ax +b (PointB)}} \right.  \\  \\  \left \{ {{4 =a*4 + b} \atop {5=a*(-1)+b}} \right.  \\  \\  \left \{ {{b= 4 -4a} \atop {5 = -a + (4 - 4a)}} \right. \\  \\   \left \{ {{b = 4 - 4a} \atop {5 - 4 = - 5a }} \right.  \\  \\  \left \{ {{b = 4 - 4a} \atop {a = -  \frac{1}{5} }} \right.  \\  \\  \left \{ {{ b = 4 - 4*(- \frac{1}{5} )= 4 +  \frac{4}{5} = 4,8} \atop {a = -  \frac{1}{5} }} \right.

<span>We insert the calculated a and b in the equation f(x) = ax + b

</span>y = -  \frac{1}{5} x + 4,8

<span>Since a> 0, the function is decreasing</span>

Explain about herb some lines​
skelet666 [1.2K]

Answer:

Herbs are small plants that have a fleshy or juicy stem when they are young. The stems of some herbs develop hard, woody tissue when they grow old. Most herbs are perennials. This means that the tops of the plants die each growing season, but the roots remain alive and produce new plants year after year.
