The given equation is

Consider the slope-intercept form.

Rewriting the given equation in the slope-intercept form.

Subtracting 3x from both sides, we get

Dividing both sides by 5, we get



Compared to the slope-intercept form, we get m=-0.6 and b=1.4.
Hence the slope m= -0.60.
#13: b
#14: c
#16: c
It is very easy, have a nice day :)
Answer: what
Step-by-step explanation:
He purchased "t" boxes for $4 and then went back later and purchased "t" boxes for $5.
4t + 5t
4t +5t = 9t
