Are these right if not please tell ill give brainlist.

b and c are wrong

Step-by-step explanation:

the slope for b is -3/7 and the slope for c is 3/10.

You can find the answer to this by using the formula (y2-y1)/(x2-x1).

You pick the endpoints or some easy points to calculate and the x and ys in the formula are you points subtract to find your slope. Also, I'm not sure if you have to put the slope in decimal form but it's usual written as a fraction. They're both correct, fraction or decimal, though.

Another thing to help, when your line is increasing it will have a positive slope if it is decreasing, then the slope will negative. You can use this to check your if your answer correct. For example, Line GH is decreasing as it grows and goes to the right, the y values decrease.

Hope this helps!

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
