Answer:
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!
