Answer:
C
Step-by-step explanation:
The general form of a line's equation is [tex]y=mx+b[/tex]
Where,
- m [the coefficient of [tex]x[/tex] ] is the slope
- b is the y-intercept
What is slope's interpretation?
The slope is the change in [tex]y[/tex] per unit of change in [tex]x[/tex]
For our problem, comparing [tex]y=8-3x[/tex] with the general form tells us that the slope is [tex]-3[/tex]. We can write [tex]-3[/tex] as [tex]\frac{-3}{1}[/tex]
Thus, we can say there is a change in [tex]y[/tex] of 3 units [decrease, because of negative sign] per unit change of [tex]x[/tex]
Hence, the change in [tex]y[/tex] variable is decrease of 3 units. Answer choice C is correct.
