Firlakuza [10]

Answer:

vertical intercept is another word for y intercept and horizontal intercept is another word for x intercept so for this problem, looking at the graph, the y intercept is (0,0) and the x intercept is (-2,0) though (0,0) could pass of as a second x intercept. But its safe to just go with (-2,0) as the x intercept while y intercept is (0,0)

Andrews [41]

Answer:

The correct answer is +45; -18; -7.

Step-by-step explanation:

Parvana records the transactions for her bank account for the week .

On Monday, Parvana deposited $45. Thus Parvana made an addition of $45 in her account. Therefore a +45 integer is used to represent this transaction into her account.

On Tuesday she used her debit card to $18 for a new shirt. Thus Parvana made a deduction of $18 from her account. Therefore a -18 integer is used to represent this transaction into her account.

On Thursday she withdrew $7 from an ATM. Thus Parvana made a deduction of $7 from her account. Therefore a -7 integer is used to represent this transaction into her account.

Thus the integers +45; -18 and -7 are used to represent transactions in Parwana's account.
