Slope is equal to y2-y1 over x2-x1, however robert put the x on the top and the y on the bottom. However, if the fraction was FLIPPED, he would be correct.

Answer:

A) Miguel: d=25t+10

gabby: d=30t

B) gabby will catch up with Miguel in 2 hours at a distance of 60 miles

Step-by-step explanation:

<u><em>Lets start of with the equation:</em></u>

There is 2 possible equations we can use for this:

  1. A) Miguel: d=25t+10  gabby: d=30t     OR
  1. D) Miguel: d=10t+25  gabby: d= 30t

The resonable response for this would be A because Miguel starts off with 10 miles so you would add 10 to your equation so response D is incorrect because you are not multiplying 10t, but rather 25t.

<u><em>Now let's do the actual answer</em></u>

There is 2 possible answer for this:

  1. B) gabby will catch up with Miguel in 2 hours at a distance of 60 miles
  2. C) gabby will catch up with Miguel in 1.25 at a distance of 37.5 miles

The response that would make the most sense would be B. Let me explain

We are going to be using response C for now. You would have to multiply Miguel: 25(1.25) + 10

31.25 + 10

=41.25

Gabby: 30(1.25)

= 37.50

Miguel is still ahead of Gabby so Answer C is incorrect

We are going to be using response B now. You would have to multiply

Miguel: 25(2) + 10

50 + 10

=60

Gabby: 30(2)

=60

Now they are both the same mile so this would mean Answer B is correct

plz give brainliest :'D
