Best ResponseYou've already chosen the best response.0by graphing, you can find the point of intersection as the solution.

Best ResponseYou've already chosen the best response.0first you plot the graph of these linear equations. they are straight lines. 4xy=15 is y=4x15 which 15 is the yintercept. to find the xintercept, substitue y=0 into the equation. 0=4x15 implies x=15/4. now u can draw the straight line. same goes on x+5y=12. change it to y=mx+c then you'll get the yintercept. to find xintercept, substitute y=0. after that plot them and you'll get another straight line. after plotting, you can see there is a point of intersection which is the solution of this linear system.

Best ResponseYou've already chosen the best response.0plot the xintercept and yintercept that you obtained and draw a line pass through the points :)

Best ResponseYou've already chosen the best response.0for 4xy=15, you have xintercept = 15/4 and yintercept = 15. put a dot on x=15/4 on xaxis and put a dot on y=15 at yaxis.

Best ResponseYou've already chosen the best response.0then draw a straight line that pass through both of the dots. okay?

Best ResponseYou've already chosen the best response.015/4 = 3 and 3/4. plot it in between 3 and 4 but close to 4 since the ratio is 3/4.

Best ResponseYou've already chosen the best response.0so it would be (0,3/4)?

Best ResponseYou've already chosen the best response.015/4 is the xintercept, you should draw it on xaxis. the coordinate is (15/4, 0). 15/4 is an improper fraction. you can change it into mixed number and you'll get 3+3/4 which is between 3 and 4 :)

Best ResponseYou've already chosen the best response.0ok so i put a dot on (0,15) and between 3 and 4 what about the 2nd equation of x+5y=12

Best ResponseYou've already chosen the best response.0you're right. now we proceed to the next line. try to rearrange it into general form, y=mx+c.

Best ResponseYou've already chosen the best response.05y=x12, divide all by 5, you'll get y=x/5 12/5. now you know the yintercept is 12/5. try substituting y=0 and find the x value. that's how you obtain the xintercept.
