    extract y from the equation and then find the slope, by comparing the equation with y=mx+c where m is the slope

    when x = 0 ; y = 7/3 wne y = 0 ; x = 7/5

    Now in the equation put x=0 and find what y is and then do the same for y that is put y = 0 and find what x is

    dont need slope with this equation; you could do it, but its extra work

    I understand that but if a student asks this question, and if I tell him or her to find the slope, he or she will think on it, and eventually gain a better picture.

    We perhaps are the reason for the creation, and we tried to create light and unintentionally created darkness, we tried to create matter and created antimatter, we tried to create happiness and created sadness. We only wanted the good things from the creation, but the damned creation told us to create good you need to create bad or evil so as to actually contrast the goodness. I wish it ends now.

    We never felt that we can't draw a white line on a white sheet. We only wanted to draw white lines, but had to create a black sheet for the same If the creator would have realized a bit of this before creation; no creation would have ever occured

    I didn mean you to feel bad. When I help my friend I used to use graphs. This makes everything clear. And perhaps for us drawing a lines is easy, however for somebody else it can be a big issue. So draws can be helpful to some extent.

    make x=0 and solve for y 0 + 2y = 11; y = 11/2

    How to draw a line. The first thing you have to do is: 1) find the x-intercexion and the y-intersexion. X-interseccion (y=0) -5x+2(0)=11 so x=11/-5

    in order to find Y-Interseccion (x=0), we do the following: -5(0)+2y=11 so y=11/2

    thats the easiest way; another way is to get y alone 2y = 5x+11 y = 5x/2 + 11/2 now any number you use for x will make a y and plot the points

    No problem my friend, we are here to help you. So the final thing (step 2) is to plot the two point we just got. They are: Point1=(-11/5;0) Point2=(0,11/2 ) Plot this two numbers and join them with a line and this is the draw you want. Any question, please ask

    ahhh ok I now know what you want. You have to list different values for x and y isolating y y=(5x+11)/2 now you have to choose values for x, replace them in the last formula and find y. for example. X Y ------- 0 -> 5.5 1 -> 8 2 -> 10.5 the points are: p1=(0;5.5) p2=(1;8) p3=(2;10.5) insert this three point in your graph and you must hopefuly be done :)
