Refer to the attached image.
Given:
The measure of 
and 
.
Also, Three rays ML, MK, and MJ share an endpoint M. Ray MK forms a bisector as shown in the attached image and the bisector divides angle JML into two parts.
To Prove: 
is a right angle.
Proof:
Statements Reasons
1. 
Given
2. 
Given
3. 
The reason for statement 3 is Angle addition postulate. As angle JML is composed of 2 angles that is angle JMK and angle KML. So by adding the measures of angles JMK and KML, we will get the measure of angle JML which is referred as Angle addition postulate.
4. 
Substitution property of equality
5. 
Simplification
6. 
JML is a right angle. Definition of right angle
so basically what you would have to do is set up your numbers. it would look something like this. 68
× 49
-------------
and would then multiply 9 by 8, 9 by 6. put it down below the line while making sure to carry the numbers if need be. then do the same with the 4 times 8, and 4 by 6.
Answer
Attached the graph
Step by step explanation
Y = -1/4z + 5
Let's form the table values
Here z is the independent variable and y is the dependent values.
Let's take z = -1, 0, 1, 2 and find the corresponding y-values
<u>z y</u>
-1 5.25
0 5
1 4.75
2 4.5
Now let's plot the points and draw the graph.
Here is the graph.
There you go!!! Answer is at the very bottom. let me know if you have questions
<h3>The lines intersect at (x,y) = (6,2)</h3>
This is simply because the x coordinate is 6 and the y coordinate is 2.
The line x = 6 is a vertical line in which all points on it have an x coordinate of 6. It goes through 6 on the x axis.
The line y = 2 is horizontal where all points on it have a y coordinate of 2.
The vertical and horizontal lines intersect at (6,2)
