Hello!
The most logical equation would be b)
Hope it helps, have a nice day!
Answer:
y = 1/3x + 10/3
Step-by-step explanation:
→ Write gradient into format
y = 1/3x + c
→ Substitute in (5,5)
5 = 5/3 + c
→ Find c
c = 5 - 5/3 = 10/3
→ Finish off
y = 1/3x + 10/3
Answer:
The value of y is -2
Therefore the given point (8,y) becomes (8,-2)
Step-by-step explanation:
Step-by-step explanation:
Given that the line through the points (8, y) and (9, 1) and slope m is 3
To find y to the line through the points (8, y) and (9, 1) :
The formula for slope is ![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
,
be the given points (8, y) and (9, 1) respectively
Now substitute the values of the points and m=3 in the formula
![3=\frac{1-y}{9-8}](https://tex.z-dn.net/?f=3%3D%5Cfrac%7B1-y%7D%7B9-8%7D)
![3=\frac{1-y}{1}](https://tex.z-dn.net/?f=3%3D%5Cfrac%7B1-y%7D%7B1%7D)
![3=1-y](https://tex.z-dn.net/?f=3%3D1-y)
![3-(1-y)=1-y-(1-y)](https://tex.z-dn.net/?f=3-%281-y%29%3D1-y-%281-y%29)
![3-1+y=1-y-1+y](https://tex.z-dn.net/?f=3-1%2By%3D1-y-1%2By)
( adding the like terms )
![2+y-2=0-2](https://tex.z-dn.net/?f=2%2By-2%3D0-2)
Therefore y=-2
Therefore the value of y is -2
Therefore the given point (8,y) becomes (8,-2)
