The line models maria's saving account. she started with 7 in her account. she saves three each day. write an equation for the line in slop intercept form where x is the number of days she saves and y is the total amount in her account.

y=7+3x

Step-by-step explanation:

Since she already has 7 in her account and she ADDS 3 more each day you would multiply 3 by x which represents the number of days and add that to seven because she already had it. This would equal to Y which represents the total in her account
