Write the general form of the equation of the line through t
Write the general form of the equation of the line through this pair of points. (-4, -8) and (-10, 7) The equation is = 0. (Simplify your answer.)
Solution
( -4 , -8 ) and ( -10 , 7 )
slope = y2 - y1 / x2 - x1
m = ( 7 + 8 ) / (-10 + 4 )
m = -15/ 6 = -5 / 2
applying point slope form
y - y1 = m ( x - x1 )
y + 8 = -5/2 ( x + 4 )
y + 8 = -5/2 x - 10
multiplying both sides by 2
2y + 16 = -5x - 20
therefore equation is
5x + 2y + 36 = 0
