Minchanka [31]3 years ago

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!

Ira Lisetskai [31]

Answer:

3 hours 8 seconds

Step-by-step explanation:

Juan and Andrés are older adults and marathoners. Today they participated in the international marathon of the Andes. The announcer who covers this sporting event reported that Juan had finished the race with a time of 3¾ hours. Tijuanito the route in ⅔ of hours more than Andrés, how long did Andrés finish the marathon ?.

It is given that,

Juan had finished the race with a time of 3¾ hours.

He takes ⅔ of hours more than Andrés.

We need to find how long did Andrés finish the marathon.

Time taken by Juan = \dfrac{15}{4} hours

Time taken by Tijuanito is \dfrac{2}{3} hours more than Andrés.

So, Andrés finish the marathon \dfrac{15}{4}-\dfrac{2}{3}=3.08\ \text{hours} before.

y=-3x-2

Step-by-step explanation:

so the line is going down so we know that the slope is going to be negative.

slope is y over x and it looks like every time it goes up 3 and to the right 1 so 3/1 is 3 so the slope is 3 and if the slope has to be negative than the answer is the first one
