Answer 2

Point A ( 2, 15 )

Point B ( –3 , – 5 )

Equation of line using two point form

( y – y1 ) = [ ( y2 – y1 ) / ( x2 – x1 ) ] ( x – x1 )

( y – 15 ) = [ ( – 5 – 15 ) / ( – 3 – 2 ) ] ( x – 2 )

y – 15 = ( – 20 / – 5 ) ( x – 2 )

y – 15 = 4 ( x – 2 )

y – 15 = 4x – 8

y = 4x – 8 + 15

y = 4x + 7

4x – y + 7 = 0
