Answer:
The line passes through (4, -7) and (5, -10).
Step-by-step explanation:
When x = 4, y = 5 - 3(4), or 5 - 12, or -7. Thus the point (4, -7) lies on the graph. Similarly y = 5 - 3(5) = -10 when x = 5. Thus, the line also goes through (5, -10). Plot these two points and draw a line through them. Doing this will result in the desired graph.
Simply 5. Absolute value is most commonly used to show that even though what is in the brackets is negative [-7] the actual value for practical purposes needed is positive 7.

Answer:
A. Her expenses are $25 per week.
Step-by-step explanation:
Using a linear function f(x) = mx + b, m= slope and b = y-intercept or initial value. With the values of the given function: E(x) = 7x - 25, we can determine that the overall earnings (E(x)) is based on a profit of $7 per door ('x') and that if Jessica is subtracting $25 from her earnings, that this must be the cost per week for her expenses. So, she would need to knock on a minimum of 4 doors each week in order to make a profit.
