3 casseroles feeds 15 people
The ratio is 3:15
If you divide each of those by 3, youll find that 1 casserole feeds 5 people
1 : 5 is the ratio.
Divide 30 by 5 = 6
6 casseroles feeds 30 people.
6 : 30
35 divided by 5 = 7
7 casseroles feed 35 people
7 : 35
Answer:
Part 1) The graph in the attached figure
Part 2) The equation of the line is
Step-by-step explanation:
Part 1) we know that
To graph a line we need at least two points
we have
(5,2) and (0,7)
Plot the points
Connect then and join to graph the line
The graph in the attached figure
Part 2) Determine the equation of the line
Find the slope
Remember that the formula of slope is "rise over run", where the "rise" (means change in y, up or down) and the "run" (means change in x, left or right)
see the graph
The formula to calculate the slope between two points is equal to
we have
substitute
Is negative because is a a decreasing function
as the value of x increases, the value of y decreases
The equation of the line in slope intercept form is equal to
we have
----> the y-intercept is given see the graph
substitute
