Answer: 
 6x - y + 7 = 0 
 Step-by-step explanation: 
 To find the equation of line passing through a point and slope of same line is given, we use formula, 
 y - y₁ = m ( x ₋ x₁) 
 where, (x₁, y₁) = (6, 43) 
 and m is a slope of line passing through (x₁, y₁) which is equal to 6. 
 Substituting all values in above formula. We get, 
 ⇒ y - 43 = 6 ( x ₋ 6) 
 ⇒ y - 43 = 6x - 36 
 ⇒ 6x - y + 7 = 0 
 which is required equation.
