Help please =*(
Line K is in the rectangular coordinate system. If line K is defined by the equation 3y=2x+6 and line K intersects the xaxis at point (a, b), then what is the value of a?

Best ResponseYou've already chosen the best response.0Okay i know the answer to this i need to know why we multiply the Y by 0 instead of the yintercept.

Best ResponseYou've already chosen the best response.0ook... don't know why Y gets multiplied by 0 in your given solution... but maybe it was smth like: any point on x axis is (x, 0)

Best ResponseYou've already chosen the best response.1like i said yesterday (a,b) < b is ycoordinate not yintercept (b)

Best ResponseYou've already chosen the best response.0So why is it 3(0)=2(a)+6 instead of 3=2(a)+0

Best ResponseYou've already chosen the best response.0So you need the yintercept to find the xintercept?

Best ResponseYou've already chosen the best response.1not the yintercept ycoordinate that's what you need

Best ResponseYou've already chosen the best response.0But in this case we multiplied the coordinate by 0 and used the yintercept to find the solution

Best ResponseYou've already chosen the best response.1dw:1439308325786:dw to find xintercept replace y for 0 always!!

Best ResponseYou've already chosen the best response.0we didn't multiply the coordinate. actually, we used the 2nd relation of a formed system of equations (we didn't write the system) . that equation is : y = 0 (and, implicitly, x = a) , the equation of the x axis

Best ResponseYou've already chosen the best response.0the ycoordinate was made 0 not the yintercept

Best ResponseYou've already chosen the best response.0so to find the xintercept make the ycoordinate a 0 not the yintercept?

Best ResponseYou've already chosen the best response.1i forgot to tell you something there is one situation when ycoordinate = yintercept only when x=0 if slope of line is 2 passes through the point( 0 ,4) where x=0 y =4 thats mean yintercept is also 4 you don't need to plug in x and y value to solve for b ONLY WHEN x=0 (0,8) <yintercept = 8 =ycoordinate
