11c) Find the values for a and b.
11c) What is the y-coordinate when x-coordinate is 1. (1,?)

Answer 1

`a=7\\b=7\\When\ x=1, \ y=-1`

Explanation:

The line passes through the point
`(3,3)\ and\ (8,13)`.

`Slope=(13-3)/(8-3)=(10)/(5)=2`

Equation of line: Line having slope
`=2` and passing through
`(3,3)`

`y-3=2(x-3)\\y-3=2x-6\\2x-y=3`

11c)
`(5,a)` is on the line

`2* 5-a=3\\10-a=3\\a=10-3=7`

`(b,11)` is also on the line

`2* b-11=3\\2b=3+11\\2b=14\\b=7`

When
`x=1`: Substitute the value of
`x` in the equation of line.

`2* 1-y=3\\2-y=3\\y=2-3=-1`
