X increases by one
y increases by 2
(5, 1) - > (x + 1, y + 2) -> (6, 3)
Answer:
x = 33/5
Step-by-step explanation:
x - 3/5 = n.......n = 6
so we sub
x - 3/5 = 6......add 3/5 to both sides
x = 6 + 3/5...convert using common denominator of 5
x = 30/5 + 3/5
x = 33/5 <===
check...
x - 3/5 = 6
33/5 - 3/5 = 6
30/5 = 6
6 = 6 (correct)...so it checks out
Answer:
x= 3/5 or x= 0.6
Step-by-step explanation:
We have been given a table that shows a linear relationship between x and y. We are asked to find the rate of change change of y with respect to x.
To solve our given problem, we will find the slope of the line passing through the given points.
![m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
Let us find slope of line using points
and
.
![m=\frac{15-96}{-2-(-20)}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B15-96%7D%7B-2-%28-20%29%7D)
![m=\frac{-81}{-2+20}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-81%7D%7B-2%2B20%7D)
![m=\frac{-81}{18}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-81%7D%7B18%7D)
![m=-4.5](https://tex.z-dn.net/?f=m%3D-4.5)
Therefore, the rate of change of y with respect to x is
.
