Xavier and bobby each receive a salary check every week. they combine their checks in one account. after 1 week, the balance in their account is $50. after 2 weeks, the balance in their account is $100. which line, on the coordinate grid, correctly shows the amount of money xavier and bobby have combined as it changes over time? line a line b line c

It goes from 0 Plus 50 in the first week then the second week another 50 is added to the fifty dollars Xavier and Bobby had the previous week to get a hundred dollars after two weeks.

Step-by-step explanation:

step-by-step explanation:

rectangles are made up of 4 right angles, which means that a side and a base meet perpendicular to one another.   their slopes then have to reflect perpendicular slopes.   perpendicular slopes are opposite reciprocals of one another.   for example, if the slope of one line is +2/3, then the perpendicular slope to that would be -3/2.   so we look for that combination in our choices.

all of them satisfy that condition (so what's the question, i guess? )
