Veronica deposited $21 in a savings account that earns 2.4% simple interest. Which graph represents this scenario?
2 answers:
Answer:
The below graph represents this scenario.
Step-by-step explanation:
Given,
The deposited amount, P = $ 21,
Annual interest rate, r = 2.4 % = 0.024,
Thus, the simple interest after x years,
If x-axis shows the number of years and y axis represents the simple interest after x years,
So, y = 0.0504x is a line passes through the origin which will show the given scenario,
( shown below )
Also, x ≥ 0 ( number of years can not be negative )

Answer:
y = - x + 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (4, 0) ← 2 points on the line
m = = -
The line crosses the y- axis at (0, 3 ) ⇒ c = 3
y = - x + 3 ← equation of line
