Julia joined a flower delivery service. The cost to join is a one-time fee of $5 and the cost per flower arrangement is $10. Let y represent the total cost Julia will spend on x flower arrangements.

Graph this linear relationship.

Select two points to graph the line.

Answer:

Line equation is y = 10x + 5

Two points for graphing are (1, 15) and (2, 25)

Graph attached

Explanation:

The equation y = 10x + 5 provided by oldhanat00014 is correct. I am merely providing the methodology for determining the two points you need to plot the line as well as providing the graph

To find any point o the line, all you have to do is choose a value of x and determine the value of y from the equation. Choose reasonable points so that they are distinguishable

Equation: y = 10x + 5

Choose x - 1 ==> y = 10·1 + 5 = 15 Point is (1, 15)

Choose x = 2 ==> y = 10·2 + 5 = 25 Point is (2, 15)

You can also choose x = 0 when y = 5(this is called the y-intercept and is the second part of the expression 10x + 5 on the right side)

Plot these two points on the graph

Draw a straight line through them
