Answer:
Step-by-step explanation:
Given: Pauline withdrew $7.50 each day from her saving account.
She withdrew money for 3 days.
As Pauline is withdrawing the money, therefore the amount will be in negative
Now finding the expression for total amount of money withdrew.
Total money withdrew = 
∴ Total money withdrew = 
Hence, the expression to determine the total amount of money she withdrew is 
and Total money she withdrew is -$22.5
Answer: y = 90 x = 29
Step-by-step explanation:
The equation of the line will be (assuming the y-intercept equal to zero):
y = 2.5*x
<h3>
What is Tahila's mistake?</h3>
We know that we have a linear equation of the form:
y = a*x + b
Such that we know that the line passes through (-3, -7.5), notice that the proposed equation is:
y = 0.5*x
If you evaluate that in -3, you get:
y = 0.5*-3 = -1.5
So this line does not pass through (-3, -7.5).
If we assume that b = 0 in the linear equation, then we can find the value of a as:
-7.5 = a*-3
a = 7.5/3 = 2.5
Then the linear equation is:
y = 2.5*x
