A sixth grade class is painting a mural. To make a darker shade of orange they use a ratio of 5 ounces of red paint to 3 ounces of yellow paint. Use this ratio to consider the amount of yellow paint needed for each amount of red listed in the table. Determine ordered pairs for points A, D,and C and graph the relationship of the amount of red paint to the amount of yellow paint on the coordinate plane. Click to select the point. Then to place the point click the location for that point on the graph

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

step-by-step explanation:

we have

using a graphing tool

the graph in the attached figure

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)

about 0.75 hours
