Y = mx + b
slope(m) = 6
(20,220)....x = 20 and y = 220
now sub and find b, the y int
220 = 6(20) + b
220 = 120 + b
220 - 120 = b
100 = b
so ur equation is : y = 6x + 100
to graph :
y = 6x + 100.....u have a slope of 6....u have a y int of 100 or (0,100)...
I would say plot (0,100) and since ur slope is 6, go up 6 and to the right 1...but that is not to helpful because ur graph is not in intervals of 1.
So we will find some points on ur line.
y = 6x + 100....when x = 5
y = 6(5) + 100
y = 30 + 100
y = 130....so another point on ur line is (5,130)
y = 6x + 100...subbing in 10 for x
y = 6(10) + 100
y = 60 + 100
y = 160....another point is (10,160)
keep finding points this way...here are some more...
(15,190) , (20,220), (25,250)
Answer:
y-7=2(x-6)
Step-by-step explanation:
y2-y1/x2-x1
7-(-9)/6-(-2)
7+9/6+2
16/8
m=2
y-y1=m(x-x1)
y-7=2(x-6)

Step-by-step explanation:
Finding square roots of of numbers that aren't perfect squares without a calculator.
Example: Calculate the square root of 10 ( ) to 2 decimal places.
Find the two perfect square numbers it lies between.
Divide 10 by 3. ...
Average 3.33 and 3. ( ...
Repeat step 2: 10/3.1667 = 3.1579.
A square root of a number is a value that, when multiplied by itself, gives the number. Example: 4 × 4 = 16, so a square root of 16 is 4. ... The symbol is √ which always means the positive square root.

To find the average, find the mean: add all the numbers together and divide by the number there is.
First add all the numbers together:
39 + 43 + 28 + 36 + 29 = 175
Next, divide 175 (the total) by 5 (because there are 5 numbers)
175/5 = 35
35 is your average.
hope this helps
