Best ResponseYou've already chosen the best response.0Write the equation of the line that is parallel to the line 4x  3y = 12 and passes through the point (3, 4).

Best ResponseYou've already chosen the best response.1parallel lines will have the same slope...so we need to find the slope of 2x  3y = 12. Now in y = mx + b form, the slope is in the m position....so we need to turn 2x  3y = 12 into y = mx + b form. Do you know how to do that ?

Best ResponseYou've already chosen the best response.0Divide 12 by 2x, right?

Best ResponseYou've already chosen the best response.12x  3y = 12  subtract 2x from both sides 3y = 2x  12  now we need to divide both sides by 3 y = 2/3x + 4 so the number in the m position, the slope, is 2/3 are you following me ?

Best ResponseYou've already chosen the best response.0Wait, I'm not sure I understand completely. So the first step would be 3y = 14x?

Best ResponseYou've already chosen the best response.1so we have to have a slope(m) of 2/3 Now we use y = mx + b slope (m) = 2/3 (3,4)...x = 3 and y = 4 now since we have our slope and our x and y points, we need to find b, the y intercept 4 = 2/3(3) + b 4 = 6/3 + b 4 = 2 + b 4 + 2 = b 6 = b so our parallel line is : y = 2/3x + 6 questions ?

Best ResponseYou've already chosen the best response.1you are making a mistake by adding unlike terms. you cannot add 2x to and 12..they are unlike terms. 2x  3y = 12  subtract 2x from both sides 3y = 2x  12 see how I did that....

Best ResponseYou've already chosen the best response.1oops...you cannot add 2x to 12

Best ResponseYou've already chosen the best response.13y = 2x  12  now we divide both sides by 3 to get y by itself (3/3)y = (2/3)x 12/3 y = 2/3x + 4 get it ??

Best ResponseYou've already chosen the best response.0ooh ok. I understand it now. Thanks!!

Best ResponseYou've already chosen the best response.1then you just use y = mx + b and sub in your slope and your points and solve for b, the y intercept.....just like I did above.
