Given: , line equation

* To find the X & Y Intercepts of the line, we let F(x)=0 to find Y-intercept, & let F(y)=0 to find X-Intercept:
F(x)=0
---> --->
, Y-Intercept

F(y)=0
--->
, X-Intercept

Via Slope Intercept Form, , where

Following this form,
---> --->

So the slope=m is , and Y-intercept is . (Answer)

When x=16;

, (Answer)

For the .
From the Y-intercept = (0,3), we moved down 5 steps (-5), and to the right 4 steps (4).
---> See, if you keep doing that, that's where the point on the X-axis & Y-axis meet on the line.

Thank you,
Jojo
