2 guest, guest krypton is a chemical substance. krypton has a constant of proportionality between its mass and volume. the constant of proportionality is 3.75 grams/liter. use the add arrow tool to graph krypton’s proportional relationship.
Answer
# Explanation:
## Step1: Recall proportional - relationship formula
The formula for a proportional relationship is $y = kx$, where $k$ is the constant of proportionality. Here, $y$ is the mass (in grams), $x$ is the volume (in liters), and $k = 3.75$ grams/liter. So the equation is $y=3.75x$.
## Step2: Find points to plot
When $x = 0$, $y=3.75\times0 = 0$. When $x = 2$, $y=3.75\times2=7.5$. When $x = 4$, $y = 3.75\times4 = 15$. When $x=6$, $y=3.75\times6 = 22.5$. When $x = 8$, $y=3.75\times8=30$. When $x = 10$, $y=3.75\times10 = 37.5$. When $x = 12$, $y=3.75\times12=45$.
## Step3: Plot and draw the line
Plot the points $(0,0)$, $(2,7.5)$, $(4,15)$, $(6,22.5)$, $(8,30)$, $(10,37.5)$, $(12,45)$ on the graph and use the Add - Arrow tool to draw a straight line passing through these points starting from the origin $(0,0)$.
# Answer:
Graph a straight - line passing through the origin $(0,0)$ with points such as $(2,7.5)$, $(4,15)$, $(6,22.5)$, $(8,30)$, $(10,37.5)$, $(12,45)$ using the Add - Arrow tool.
