Change in y over change in x
Step-by-step explanation:
To make this easier to understand lets make a table
<u> x | y </u>
1 | 2
2 | 4
3 | 6
Now we go back and find the slope. This is really simple as the rise and run is displayed.
- Count the change in x
In this case x changes by 1
2. Count the change in y
In this case it changes by 2
Now put it into rise over run
Rise(y)/Run(x)
your m or slope would be 2/1 or 2
and in a y=mx+b would be
y=2x+b
Thhe easiest way would be to solve for y first
4x=3y-7
add 7
4x+7=3y
divide both sides by 3
(4x+7)/3=y
try each
x=4
(4(4)+7)/3=y
(16+7)/3=y
(23)/3=y
7 and 2/3=y
(4,7.66666)
x=5
(4(5)+7)/3=y
(20+7)/3=y
(27)/3=y
9=y
(5,9)
x=6
(4(6)+7)/3=y
(24+7)/3=y
(31)/3=y
10 and 1/3=y
(6,10.333)
(4,7.66666)
(5,9)
(6,10.333)
when x=4, y=7 and 2/3
when x=5, y=9
when x=6, y=10 and 1/3
Use c^2=a^2+b^2
26^2= 13^2 + b^2
676=169 + b^2 (subtract 169 from both sides)
507= b^2 (take the square root of each side)
22.52 in. =b
I think the answer should be A n goodluck
