Skills and Applications

Using Intercept Form In Exercises 81-86, use the intercept form to find the general form of the equation of the line with the given intercepts. The intercept form of the equation of a line with intercepts $\left(a,0\right)$ and $\left(0,b\right)$ is

$\frac{x}{a}+\frac{y}{b}=1,a\ne 0,b\ne 0.$

$\begin{array}{l}\text{Point}\text{of}\text{line}:\left(1,2\right)\\ x-\text{intercept}:\left(c,0\right),c\ne 0\\ y-\text{intercept}:\left(0,c\right),c\ne 0\end{array}$
