Answer:
it is 3x-20
Step-by-step explanation:
when u multiply the three and the x you will get your anser and then u will subtract it out of 20
Given:
The graph passes through the points (0,-20) and (4,10).
To find:
The equation of line that most closely represents the line depicted in the graph.
Solution:
If a line passing through two points, then the equation of line is

The given line passes through the points (0,-20) and (4,10). So, the equation of line is




Subtracting 20 from both sides, we get

The function form is

f of x equals fifteen halves times x minus 20.
Therefore, the correct option is B.
I think the answer would be 7.5 hours or 4 hours,not so sure which one exactly
