Question

The equation of a straight line is 3x - 3y - 7 = 0. Find :
(i) the gradient of the line.
(ii) the inclination of the line.
(iii) the y-intercept of the line.​

Answer 1

Step-by-step explanation:

$3x - 3y - 7 = 0$

$3x - 3y = 7$

$- 3y + 3x - 7 = 0$

$= - 3y = - 3x + 7$

$y = \frac{ - 3x}{ - 3} - \frac{7}{ - 3}$

$m = - 1 \: \: \: \: \: \: and \: y inclination = \frac{ - 7}{3}$
