Ryan is tracking how much money he has each week.
He started with $50.
He saves $15 per week for the first 6 weeks.
He spent $10 per week after week 6 until the money's all spent.

1) The graph of this scenario would be (linear or nonlinear) because the rate of change changes.
2) The y-intercept of this graph would be
meaning
3) The rate of change is
after the first 6 weeks because as the weeks increase the money decreases.
1) The graph of this scenario would be nonlinear because the rate of change changes. From week 1 to week 6, the rate of change is constant as Ryan saves $15 per week. However, after week 6, the rate of change changes as Ryan starts spending $10 per week.
2) The y-intercept of this graph would be $50, which represents the amount of money Ryan started with before any savings or spending.
3) The rate of change is negative after the first 6 weeks because as the weeks increase, the amount of money decreases due to the spending.
You sure
Apologies for the error in my previous response. Let me correct it:
1) The graph of this scenario would be nonlinear because the rate of change changes. From week 1 to week 6, the rate of change is constant as Ryan saves $15 per week. However, after week 6, the rate of change changes as Ryan starts spending $10 per week. This change in rate indicates a nonlinear relationship between the weeks and the amount of money.
2) The y-intercept of this graph would still be $50, which represents the initial amount of money Ryan had before any savings or spending.
3) The rate of change is positive for the first 6 weeks because as the weeks increase, the amount of money saved increases due to Ryan saving $15 per week. However, after week 6, the rate of change becomes negative as Ryan starts spending $10 per week, causing the amount of money to decrease.
The equation 10x+3y=90
is in standard form. This form tells us the x and y-intercepts easily.

Michele has $55 after 2 weeks of saving money. She plans to have $105 after 7 weeks of saving.
Which equation matches this scenario?

y−55=10(x−2)
y minus 55 is equal to 10 times open paren x minus 2 close paren
y=7x+55
y is equal to 7 x plus 55
10x+7y=55
10 x plus 7 y is equal to 55
y+7=10(x+2)
The equation that matches this scenario is:
y−55=10(x−2)
