This is a linear equation y = mx+b, where m is the slope and b, the y-intercept.
Since we know this graph passes through A(1,4) and B(5,6), we can find easily the equation:
1st- Calculate m = (y₂-y₁)/(x₂-x₁) → m = (6-4)/5-1) = 2/4 →m =1/2
Now y = (1/2) + b.
2nd. To calculate b, replace x and y by either the coordinate of A(1,4) or B(5,6)
Let's take A where x = 1 and y = 4 for instance:
y =(1/2)x + b
4=(1/2)(1) + b
4=1/2 + b
4-1/2 = b and b= 7/2
Finally te equation becomes: y = (1/2)x + 7/2
Answer: I believe the answer is around/about 56.55
Step-by-step explanation: C=2πr=2·π·9≈ 56.54 or aound 56.52
Formula: C=2πr
Simplified Equation:
2 x 3.14 x 9= 56.52 - 56.55
Good luck!! I hope this helps! All you have to do is memorize the formula, break down & simplify the numbers and equation and you're golden!!
Edit: I reccomend checking out Khan Academy for math help!
Answer:
its third one
Step-by-step explanation:
y= -2
-2=[3x(-5/3)+5]-2
0= -5+5
0=0
