Question

How do you find point-slope form given x-intercept=9 and y-intercept=-4?

Answer 1

`y= 4/9(x-9)`

Explanation:

The line joining the two intercepts is depicted in the figure. The slope of the line would be `tan theta` as shown there.

Slope of this line would be `4/9`. It passes through point (9,0), hence point slope form would be

`y-0= 4/9 (x-9)` or simply `y= 4/9(x-9)`
