Answer 1

We can use the two point form to find the answer:

`y1 - y2 = m(x1 - x2)`
Where y1 is the y coordinate(coordinate on the right hand side of (-9)) of the of the first coordinates, and y2 is the y coordinates of the second coordinates given (0).

While x1(-9) and x2(-6) are the x-coordinates(left hand side of the coordinates) of the coordinates given seperately.

m is the slope of the two points, and the formula is:

`(y1 - y2)/(x1 - x2)`
In this case:

`( - 9 - ( 0))/( - 9 - (-6)) \\ = ( - 9 )/( - 9 + 6 ) \\ = ( - 9)/( -3 ) \\ = 3`

We can then proceed to find the eqaution by putting *one* of the points into the two-point formula.

Put (-6，0) into the formula:
-0-y = 3(-6-x)
-y = -18 - 3x
y = -(-18 - 3x)
y = 18 + 3x

Therefore the answer is y= 18+3x.

Hope it helps!
