Question

Asher opened a savings account by making an initial deposit and setting up weekly automatic deposits as shown in the graph. How much was Asher's initial deposit?
what is the amount of Asher's weekly deposit?
write and equation to represent the situation?

Answer 1

Answer:

• y = 7.5x + 20

Step-by-step explanation:

As per the graph, the y-intercept is 20 which is the initial amount.

Another marked point has coordinates (4, 50).

The slope is:

• m = (50 - 20)/4 = 7.5

The equation of the line is:

• y = 7.5x + 20

$20 is the initial deposit and weekly deposit is $7.5

Answer 2

Answer:

20 is the initial deposit and weekly deposit is $7.5
