Question

Please help these lessons are confusing me

Answer 1

y-9=17x+119

Explanation:

given points (-8,-8) & (-7,9)

let's take (-7,9) as (x1,y1) and (-8,-8) as (x2,y2)

now for finding out equation through two points, we use

`(x-x_(1) )/(x_(1)-x_(2)  ) =(y-y_(1) )/(y_(1)-y_(2)  )`

So accordingly, we input the values

`(x-(-7) )/(-7-(-8))  } =(y-9 )/(9-(-8)  )`

`(x+7 )/(-7+8)  } =(y-9 )/(9+8  )`

`(x+7 )/(1)  } =(y-9 )/(17 )`

`17(x+7) = y-9`

`17x+119 = y-9`

Answer 2

Answer: y-9 = 17(x+7)

Explanation:

We will use the second coordinate point to use in the equation and the first coordinate (-8, -8) to figure out the slope of this line.
