<span>m=(2y-y1)/(x2-x1) thats your answer</span>
Answer:
The answer is B
Step-by-step explanation:
1)
These are in Y = MX + B form
The first line has a positive slope, so the coefficient "M" is positive.
The second line has a negative slope, so the coefficient "M" is negative.
2)
The first line has a filled in dot at Y = 2.
Since it's to the left (less than X direction)...
X <= 0
The second has an empty circle at Y = 4.
Since the line goes to the right....
0 < X
3)
Also, the "+2" and the "+4" in the equation as the "+ B" indicates where each line will cross the Y axis.
From these things, we can infer that B is the correct answer.
Start the line at 3 on the y-axis (vertical). then go down two boxes and to the right three & make a mark at that point. keep going down two and over three until the end of the graph. then just connect the marks.
Answer:
Slope is 5/8.
y-intercept is (0, 5/2)
Step-by-step explanation:
Answer:
m∠1= 41°
m∠2= 85°
m∠3= 95°
m∠4= 85°
m∠5= 36°
m∠6= 49°
m∠7= 106°
Step-by-step explanation:
<u>To find m∠2</u>
95+m∠2= 180
-95 - 95
m∠2= 85
<u>To find m∠4</u>
Since they are vertical angles, m∠2=m∠4, that means that they are both 85°
<u>To find m∠1</u>
There is four angles in this shape, so the sum is 360 degrees.
90+144+85+m∠1= 360
319+m∠1= 360
-319 -319
m∠1= 41°
<u>To find m∠5</u>
144+m∠5= 180
-144 -144
m∠5= 36°
<u>To find m∠6</u>
m∠5+m∠3+m∠6= 180
36+95+m∠6= 180
131+m∠6= 180
-131 -131
m∠= 49°
<u>To find m∠7</u>
You need to find the sum of the other unidentified angle.
m∠6+m∠=180
49+m∠= 180
-49 -49
m∠= 131
Now you need to find the sum of all the angles in the quadrilateral to get the measure for angle 7.
131+38+85+m∠7= 360
254+m∠7= 360
-254 -254
m∠= 106°
