Jennifer started with 50 dollars in her savings account. Each week she withdrew 10 dollars. The amount of money in her savings account after x amount of weeks is represented by the function f(x)=50-10x. There is no money after 6 weeks.

Answer:

x intercept: 5

y intercept: 50

Step-by-step explanation:

  • let us plot the graph for better understanding.
  • we will represent f(x) on y-axis so, the equation will become: y= 50-10x
  • the equation is of the form : y=mx+c

[where, m: slope of the line

c : y-intercept ]

  • meaning of x intercept:  the x-coordinate of the point where the line meets x-axis
  • meaning of y intercept:  the y-coordinate of the point where the line meets y-axis
  • the line y= 50-10x has slope of -10 and it passes through (0,50)

[ (0,50) lies on the line only. substitute and check if the point satisfies the above line equation]

  • by seeing the graph in the attachment and by the definitions given above, we can say that,

x intercept:  5

y intercept: 50
