 Question 274972: write the equation of a line in standard form if m=-3/5 and contains (7, -11) Answer by dabanfield(803)   (Show Source): You can put this solution on YOUR website!write the equation of a line in standard form if m=-3/5 and contains (7, -11) One standard form of a line is the slope-intercept: y = m*x + b In this form m is the slope of the line and b is the value of y when x is zero( that is the value of y where the line crosses the y-axis). In this case m = -3/5 so we have: y = (-3/5)*x + b Since the line passes through the point (7,-11) we know that when x = 7, y = -11. So substituting in the equation above we have: -11 = (-3/5)*7 + b -11 = -21/5 + b b = 21/5 - 55/5 = -34/5 The equation of the line then is: y = (-3/5)*x - 34/5
