Answer:
If a line has a positive slope (i.e. m > 0), then y always increases when x increases and y always decreases when x decreases. Thus, the graph of the line starts at the bottom left and goes towards the top right.
Often, however, the slope of a line is negative. A negative slope implies that y always decreases when x increases and y always increases when x decreases
Step-by-step explanation:
yeah
There are infinitely many solutions because the two equations are the same line.
D = 15(t + 1)
Explanation:
It would be t + 1 rather than t - 1 because he has one *more* hour compared to the other riders.
The reason why t + 1 is in parentheses is because when solving, you'd have to first add instead of multiply.
