Question

help me graph this??
3x + 5y < 10
x – 4y 12

Answer 1

its suposed to be two lines that intercept each other

Answer 2

3x+5y<10 rearrange to get 5y<10-3x and again to \[y < 2 - \frac{ 3 }{ 5 } x\]
Please rewrite the second equation, I can't see what inequality it is between the 4y and 12.

Answer 3

this is what I have s far x<10/3-5y/3 and x<- 4y+12

Answer 4

ok so for the second equation 4y<12-x -> \[y < 3 - \frac{ x }{ 4 }\]
If you pretend that those inequality signs are equals signs, are you able to draw those graphs?

Answer 5

nope I am having trouble with graphing

Answer 6

For each equation pick a few x terms (say 0, 1 and 2 to make it easy) and see what y value you get. Then plot the 3 points and draw a line through them.

Answer 7

ok I figured out the fisrt line

Answer 8

the sectond line is supposed to be dashed right?

Answer 9

I'm not sure what you've graphed there but I don't think it's any of the equations you had.
Hint: when the equation of the line is y=mx+c, c is the y intercept and m is the gradient (slope). One should cross the y axis at 2 and the other at 3.

Answer 10

here are the posible graphs

Is what it should look like.
