Show hintHide hint
Think about the definition of x-intercept.
Question 5.
A recipe calls for 2 cups of flour and 3 cups of sugar. If your budget allows for a linear relationship of total cost as $C(x) = 5x + 10$ where $x$ is the number of batches, how will the total cost change with additional batches?
Show hintHide hint
Consider how each added batch impacts the overall cost in a linear manner.
Question 6.
If two lines are given by their equations $y = 3x + 4$ and $y = -\frac{1}{3}x + 2$ , determine if they are parallel, perpendicular, or neither.
Show hintHide hint
