When two lines cross, there are four angles at the place where they cross.
Two angles that do NOT share a side are vertical angles. There are two pairs
of vertical angles where the lines cross.
Also, by the way, vertical angles are always equal to each other. It's often
very helpful to know that.
Answer:
equation of the line is y=x+1
Step-by-step explanation:
the equation of a line has the form y = mx + b
while m is for the slope and b is for the y-intercept.
you can see from the graph that the line intercepts the y-axis at y=1 this is the b.
you can get the slope of the graph by taking two points from the graph lets say (1, 2) and (3, 4) then using this formula:
<h2>
![m = \frac{y_{2}-y_{1} }{x_{2}-x_{1} }](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7By_%7B2%7D-y_%7B1%7D%20%20%7D%7Bx_%7B2%7D-x_%7B1%7D%20%20%7D)
</h2>
in our case it will be:
![m=\frac{4-2}{3-1} = \frac{2}{2}=1](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B4-2%7D%7B3-1%7D%20%3D%20%5Cfrac%7B2%7D%7B2%7D%3D1)
then just substitute the values for m and b.
Answer:
B negative
Step-by-step explanation:
use real numbers?
n is +9
m is -11
m/n * (-m*n^2)
-11/9 * (11*81)
-11/1 * (11*9)
-11 * 99
-1089
A
The hidden information is that angleACB is equal to angle DCE
