Question

How would you graph this equation: x-4y=8

Answer 1

would u just minus the x to the other side and end up with -4y=-x+8?

Answer 2

then you have to divide by -4. do you know what to do from there?

Answer 3

oh, hold on

Answer 4

isolate the y. x= 8+4y, then x-8=4y, then (x-8)/4=y, and sometimes it is easier to see in standard y=mx+b so y=x/4-2=y. I'll let you do the algebra to figure how i simlified it.

Answer 5

now you can plot y vs x

Answer 6

after you divide the -4y to both sides dont you end up with: y= -1/4x+2

Answer 7

*-2

Answer 8

yes :)

Answer 9

you could do this. the way you started would give -4y=8-x then y=(8-x)/(-4 ), then y = -2 +x/4 = y. same result :). good job.

Answer 10

thanks guys! :D

Answer 11

good luck

Answer 12

im going to draw the graph. hold on

Answer 13

b is the intercept and m is the slope. in this case we have a negative intercept and a positive slope. good luck. gtg.
