Answer :
[tex]\sf\longmapsto y=-3x[/tex]
Compare to slope intercept form
[tex]\sf\longmapsto y=mx+b[/tex]
- Rate of change=m=-3
- y intercept=b=0
Initial value
[tex]\sf\longmapsto y=-3x+0[/tex]
[tex]\sf\longmapsto y=-3x[/tex]
Compare to slope intercept form
[tex]\sf\longmapsto y=mx+b[/tex]
Initial value
[tex]\sf\longmapsto y=-3x+0[/tex]
