How would I go about this maths question?

Draw the graph of 2y+3x=9
Make y the subject ---> 2y = -3x + 9 therefore y = (-3x+9)/2. Sub in some x values, get some y values, plot them :smile:
make y the subject, then when y = 0, whats x, repeat for y and then plot it down and use a ruler to draw a line between the 2 points

rearrange for y and then plot some points.

Rearrange equation and you have y=9232x y=\frac{9}{2}-\frac{3}{2}x and I'm assuming you can sketch graphs of the form y=mx+c y=mx+c ?
