Concept used:The general equation of a line is y = mx + c where m is the slope and c is any constantThe slope of parallel lines is equal.The slope of the perpendicular line have their product = “1 Equation of a line with slope m and passing through (x1, y1)(y “ y1) = m (x “ x1)Calculation:Given the line has the slope 3 and passes through (3, 4)? Equation of the line is(y “ y1) = m(x “ x1)? y “ 4 = 3 (x “ 3)? y “ 4 = 3x “ 9? y “ 3x + 5 = 0 or 3x - y - 5 = 0
