Answer:
d = √(x²~x¹)² + (y²-y1)²
Step-by-step explanation:
√(1--3)² + (7-2)²
the square root covers everything
then put this answer on the calculator
Answer:
<h2>y = 6x + 2</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept</em>
<em />
We have the slope <em>m = 6</em>, and the y-intercept <em>b = 2</em>.
Substitute:
![y=6x+2](https://tex.z-dn.net/?f=y%3D6x%2B2)
Equation that fits best in data is
.Although there are no options , kindly match this equation to options available!
<u>Step-by-step explanation:</u>
We are given a graph with y & x-axis , with 4 points given and best fit for data can be found out by joining points . On joining points , we see that best fit is a line . General equation of a line is :
,
where m = slope of line & c = intercept.
Let's calculate slope m :
Consider any two given points , let's have ( 4,0) & (3,30) :
Slope = m
⇒ m = ![\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
⇒ m = ![\frac{0-30}{4-3}](https://tex.z-dn.net/?f=%5Cfrac%7B0-30%7D%7B4-3%7D)
⇒ m = ![-30](https://tex.z-dn.net/?f=-30)
So , equation now becomes :
⇒ ![y = -30x + c](https://tex.z-dn.net/?f=y%20%3D%20-30x%20%2B%20c)
at x = 0 we have y = 4
![y = -30x + c](https://tex.z-dn.net/?f=y%20%3D%20-30x%20%2B%20c)
![4 = -30(0) + c](https://tex.z-dn.net/?f=4%20%3D%20-30%280%29%20%2B%20c)
![c = 4](https://tex.z-dn.net/?f=c%20%3D%204)
Therefore, equation that fits best in data is
.Although there are no options , kindly match this equation to options available!
