Answer 1

Maya and Mariah are twins that are saving up for college. Both girls have jobs outside of school and are trying to put together a savings plan. Maya starts her account with $80 and saved $10 per week. Mariah starts her account with $100 and saved $5 per week. b) Graph the equations on the coordinate plane below.​

Let

x ------> number of weeks

y -----> amount saved

we have

Maya's equation

y=10x+80

Mariah's equation

y=5x+100

using a graphing tool

see the attached image

please wait a minute

with the points (0,100) , (0,80) and (4,120) you can draw the two lines
