Find the slope of the line on the graph using your chosen points. Remember to use RISE / RUN. Simplify your slope. The graph doesn’t count by ones! Use the values on the graph to find the slope.
The points I chose were (3, 30) and (12 , 120)
This is a view of the graph:
The first number near 0 going up once on the Y axis is 15
Next is 30, then 45 then 60 then 75 then 90 then 105 then 120. This is all on the Y Axis going up.
Now the X Axis is 3, 6, 9, 12, 15
On the Y axis is labeled as "amount paid (in dollars"
On the X axis is labeled as "# of bags of popcorn"
To find the slope of the line using the chosen points (3, 30) and (12, 120), we can use the formula:
slope = (change in y)/(change in x)
First, let's calculate the change in y:
change in y = 120 - 30 = 90
Next, let's calculate the change in x:
change in x = 12 - 3 = 9
Now, we can calculate the slope:
slope = (change in y)/(change in x) = 90/9 = 10
Therefore, the slope of the line on the graph is 10.
how would it be written as in Y = Kx
To write the equation of the line in the form y = kx, where y represents the amount paid (in dollars) and x represents the number of bags of popcorn, we need to find the value of k.
Given that the slope of the line is 10, we can substitute this value for k in the equation:
y = 10x
So, the equation of the line would be y = 10x.
To find the slope of the line using the given points (3, 30) and (12, 120), we can use the formula for slope:
Slope = (change in y-values) / (change in x-values)
In this case, the change in y-values is 120 - 30 = 90 and the change in x-values is 12 - 3 = 9.
Therefore, the slope is:
Slope = 90 / 9 = 10
So the slope of the line is 10.
