1. Johanna was saving her allowance to buy a bicycle that cost $225. She has $25 in her savings and intends to save an additional $15 per week.
Slope = \($15\) per week
y-intercept = \((0,25)\)
2. The cost to prepare tacos can be represented by the linear equation \(c=\Large \frac{5}{4}\normalsize n+0.75\), where \(c\) represents the cost of making tacos, and \(n\) represents the number of tacos made.
Slope = \(\large\frac{5}{4}\) dollars per taco or $1.25 per taco.
y-intercept = \((0, 0.75)\)
3. The following is a graphical representation of the number of squares in each step of a linear growth pattern. Graph is created using Desmos.com.
Slope = \(-5\) squares per step
y-intercept = \((0,25)\)
4. The table below represents the distance traveled (in miles) over time (in hours).
| Time (hours) | Distance Traveled (miles) |
|---|---|
| \(2\) | \(10\) |
| \(3\) | \(13.5\) |
| \(4\) | \(17\) |
| \(5\) | \(20.5\) |
Slope = \(3.5\) miles per hour
\(y\)-intercept = \((0,3)\)
