Answer:
B
Step-by-step explanation:
The line on the left has a slope of 2 and a y- intercept of + 2, thus
y = 2x + 2 ← equation of line in y = mx + b form
It starts with a solid circle at (0, 2) indicating it can equal this value.
Thus
2x + 2 if x ≤ 0
The line on the right has a slope of - [tex]\frac{4}{3}[/tex] and a y- intercept of 4
y = - [tex]\frac{4}{3}[/tex] + 4 ← equation of line in y = mx + b form
It is valid for values of x greater than zero, thus
- [tex]\frac{4}{3}[/tex] x + 4 if x > 0
The required definition is B
