Question

What is the sum of the intercepts on the co-ordinate axes made by the line $3x+4y=12$?

Answer 1

The following are some forms of equation of straight line.
(i) Gradient form :
(ii) Point slope form : $y-y_1=m(x-x_1)$
(iii) Two points form : $y-y_1=\left(\frac{y_2-y_1}{x_2-x_1}\right)(x-x_1)$
(iv) Slope-intercept form : $y=mx+x$
(v) Two intercept form : $\frac{x}{a}+\frac{y}{b}=1$
