Question

What is the equation of the line passing through ( − 1 , 4 ) and ( − 2 , 3 ) ?

Answer 1

Find the slope using the ratio of delta y over delta x.

`m=(3-4)/(-2-(-1))`

`m=(-1)/(-1)`

`m=1`

Find the y-intercept by plugging in a point.

`y=x+b`

`4=-1+b`

`b=5`

`y=x+5`

Hope this helps.

頑張って!

Answer 2

1

Explanation:

4 minus 3 is 1 over -1 -(-2) which is 1, 1 divided by 1 is 1
