Question

2x+5y=20 I rearranged it to be y=mx+c which is -2/5x+ 4... Is this right?? Also how do you put this on a sketch graph

Answer 1

that is correct

Answer 2

to graph y=mx+b
start with the y intercept which is b, and in your case 4
then draw the line from there using the slope given

Answer 3

so start at (0,4) then go to the left 2 and up 5, then connect the dots with a line, then extend the line

Answer 4

Thanks :) should the line be straight across almost?

Answer 5

it will be straight

Answer 6

Thanks for your help :)

Answer 7

you can also let x = 0 and the y intercept is 4
then let y = 0 and the x intercept is 10
then draw a line through those points
