How do I graph 6x - 3y = 12
igor_vitrenko [27]

Answer:

You will have to change this equation into slope intercept form which will be y=2x-4.

Step-by-step explanation:

To change this equation into slope-intercept form, you have to move the x. Do that by minus 6x on both sides. Once you move the x value, your equation will look like -3y=-6x+12. Now you have to divide all your three numbers by -3. Therefore your answer should be y=2x-4. Then going from there you will be able to graph this simple equation by going two spots to the right on the x-axis, and moving 4 spaces down in the y- axis.

f the pattern in the table is extended to represent more equivalent ratios for 2:6, which pair of numbers would be in the column
olasank [31]

The pair of numbers that would be in the columns, considering the proportional relationship, is given as follows:

20 would be in the column for 2, and 60 would be in the column for 6.

<h3>What is a proportional relationship?</h3>

A proportional relationship is a special linear function, with intercept having a value of zero, in which the output variable is obtained with the multiplication of the input variable and the constant of proportionality k, as shown as follows:

y = kx

The table is extended to represent more equivalent ratios for 2:6, hence the constant of the relationship is given as follows:

k = 6/2 = 3.

Hence the equation is:

y = 3x.

The values given by each column are given as follows:

  • Column 2: values of x.
  • Column 6: values of y.

When x = 20, the numeric value of the relationship is of:

y = 3 x 20 = 60.

Hence the first option is correct.
