This graph shows a proportional relationship, y=kx. What is the constant of proportionality, k?
The constant of proportionality, k is equal to 7.
What is proportionality?The term proportionality describes any relationship that is always in the same ratio.
Given that, a graph shows a proportional relationship y = kx, is in the form of equation of a line, y = mx + c, where, m is the slope, so we can say that, the k here is the slope.
Slope = y₂-y₁ / x₂-x₁
= 35-21 / 5-3
= 14 / 2
= 7
Since, the slope of the line is 7 therefore, k = 7.
Hence the constant of proportionality, k is equal to 7.

Water flows from a hose at a rate of 3 liters every 18 seconds. At this rate, how many liters of water will flow from the hose in 60 seconds?
The required liters of water that will be from the hose in 60 seconds is 10 liters.
Given that,
Water flows from a hose at a rate of 3 liters every 18 seconds. At this rate, how many liters of water will flow from the hose in 60 seconds is to be determined.
Rate of change is defined as the change in value with rest to the time is called rate of change.
Here,
Rate of the water flow = 3 / 18 = 1/6 liters per second
For 60 seconds, water flow = 1/6 [60] = 10 liters
Thus, the required liters of water that will be from the hose in 60 seconds is 10 liters.

Answer:3.25 burger, 13.00 souvenir, 19.50 pass.
Step-by-step explanation:
1:4:6 is the ratio “1/4 of the” souvenir aka 1:4. “The souvenir is two thirds” 4 is 2/3 3/3=6 hence 1:4:6
38.75-3 for the actual amount of money spent is 35.75 divided by 11 for one unit is 3.25
so for the burger 1x3.25=3.25. for the souvenir 4x3.25=13. And for the pass 6x3.25=19.5

d.
Different slopes; different y-intercepts
Please select the best answer from the choices provided

plz help i'm begging you i don't want to fail this plz help
Answer:
C
Step-by-step explanation:
Different slopes; same y-intercept
Use a graphing calculator or an online one, like desmos to help visualize
y=x minus 2
y=2x minus 2
y= negative X minus 2
y=negative 2
If you were to type this on a graphing calculator
*Notice how all of these functions intersect at the same point on the y axis . That is because they all share the same y-intercept of -2
* The slopes are all different using the rise over run method.
Slope of y=x minus 2 is 2/2 or 1
Slope of y=2x minus 2is 2/1 or 2
Slope of y=negative X minus 2 is 2/-2 or -1
Slope of y= negative 2 is 0
