According to the given table, the slope-intercept equation of the line is given by:
![y = -2x + 1](https://tex.z-dn.net/?f=y%20%3D%20-2x%20%2B%201)
The equation of a line, in <em>slope-intercept</em> form, is given by:
![y = mx + b](https://tex.z-dn.net/?f=y%20%3D%20mx%20%2B%20b)
In which:
In this problem, we are given two points, (3,-5) and (-2,5).
- The slope is given by <u>change in y divided by change in x</u>, hence:
![m = \frac{5 - (-5)}{-2 - 3} = -2](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B5%20-%20%28-5%29%7D%7B-2%20-%203%7D%20%3D%20-2)
Hence:
![y = -2x + b](https://tex.z-dn.net/?f=y%20%3D%20-2x%20%2B%20b)
Point (3,-5) means that when
, which is used to find b.
![y = -2x + b](https://tex.z-dn.net/?f=y%20%3D%20-2x%20%2B%20b)
![-5 = -2(3) + b](https://tex.z-dn.net/?f=-5%20%3D%20-2%283%29%20%2B%20b)
![b = 1](https://tex.z-dn.net/?f=b%20%3D%201)
Hence, the equation of the line is:
![y = -2x + 1](https://tex.z-dn.net/?f=y%20%3D%20-2x%20%2B%201)

Answer:
Between 1 and 3 seconds
Step-by-step explanation:
There is no change in distance ( change in y ) between 1 and 3, so she wasn't walking during that time
Answer:
30,40,50
Step-by-step explanation:
If it is a right triangle then the pythagorean theorum would work
a^2+b^2=c^2
30^2+40^2=50^2
900+1600=2500
2500=2500
this means that 30,40,50 is the right answer
*******extra********
also 30,40,50 is a pythagorean triplet
pythagorean triplets form right angles
this one came from the original triplet of 3,4,5---just multiply by 10
In the graph it is the point with x- coordinate 1 and y-coordinate - 2
Answer: f ( 1 ) = - 2
122/11....u divide 122 by 11...or how many times does 11 go into 122.
122/11 = 11.09 with a line over the 09 because it is repeating
