How do you find the slope and intercept of #3x + y = -4#?
The equation of a line in
where m represents the slope and b. the y-intercept.
The advantage to having the equation in this form is that m and b, may be extracted 'easily'.
Express 3x + y = -4 in this form.
subtract 3x from both sides
Now y = -3x - 4 is in
Hence slope = - 3 and y-intercept = - 4
