(-2) – 2 To find the value of 3y all we must do is add 1,470 and the negative factor of 2x (–2x) + 1,470 = {3y} Let “/” represent a fraction. Now we are going to find the value of 3y/3 (–2x/3) + (1,470/3) = {3y/3} Then we are going to find the value of Y (–2x/3) + 490 = {y} For this word problem, after following the steps to find it, the Y-intercept is {490} and the slope is {-2/3x} Describe how you would graph this line using the slope-intercept method. Be sure to write using complete sentences.

So now we will be putting this equation into standard form from general form. So the first step of this would be to move the 22 without a variable onto the other side of the equation to put the variables on one side and real numbers on one side. So now your equation should turn out like this x2+18x+y2+6y=-22. Next you would want to complete the square with variables 18x and 6y, in order to complete this is cutting 18 in half then multiplying it by itself which would come out to be 18-9=9 then 9x9=81 and then do the same for 6y which is 6-3=3 then
