Answer:
[tex]y=-\frac{4}{3}x+3[/tex]
Step-by-step explanation:
The formula for slope intercept form is [tex]y=mx+b[/tex], where m is slope and b is y intercept.
The slope of the line is -4/3. If you graph a line with (3,-1) in it with the slope of -4/3, it will pass 3 in the y axis.
3 is the y intercept.
Replace m with -4/3 and b with 3.
[tex]y=-\frac{4}{3}x+3[/tex]
