Distance between points in 
If P(p1,p2) and Q(q1,q2) are points on the plane , the distance between them is
We have Q(-10,-20) plotted on the coordinate grid. We also know that P is at (40, -20). We can see they have the same y-coordinate, so the distance between them is computed simply by subtracting their x-coordinates
We must locate R knowing it's vertically above Q (x-coordinate = -10) and at the same distance from point Q as point P is from point Q. That means that from R to Q there are 50 units. They-coordinate of R will be -20+50=30.
The point R is located at (-10,30)
The distance from R to P is
Answer:
y=2x-58
Explanation:
In order to write our point-slope formula (y=mx+C format), we first need to figure out the slope (m). To figure out the slope, we divide the change in y by the change in x between the two points (rise/run). The rise is 30 (2-(-28)) and the run is 15 (30-15). Therefore the slope is 2 (30/15)
This gives us:
y=2x + c
Now to figure out C (which will be the y-intercept of the graph) we substitute in the values from one of the points. So our x=30 and our y=2:
2=2(30) + c
2=60+c
2-60=c
-58=c
So now we know that our C (constant) is - 58.
Hence our point-slope formula is:
y=2x-58
Which you can test with the other point:
-28=2(15) - 58
Hope this helped!
Answer:
x= -5
Step-by-step explanation:
0.000044, because 10 to the negative fith is 0.00001, and 0.0001 times 4.4 is 0.000044
