Anna road a horse to school wich was 25 miles she saw nancy and said if she wanted to go to the store it was 5 miles .how many miles did she walk

She never walked..? Since Anna went on a horse.., question is kind of vague
Anyway, If you count riding a horse to school as walking then it would be 30 miles in total since she went 5 miles with Nancy
If you don't count the horse riding it would be 5 miles since she walked the remaining miles with Nancy to the store

Step-by-step explanation:

Hi there!

What we need to know:

Linear equations are typically organized in slope-intercept form: where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)Parallel lines always have the same slope (m) and different y-intercepts (b)

1) Determine the slope (m)

Rearrange this equation into slope-intercept form (this will make it easier for us to identify the slope)

Subtract x from both sides to isolate 2y

Divide both sides by 2 to isolate y

Now, we can see clearly that is in the place of m. Because parallel lines have the same slope, is therefore the slope of the line we're currently solving for. Plug into :

2) Determine the y-intercept

Plug in the point (8,-7)

Add 4 to both sides

Therefore, the y-intercept is -3. Plug this back into :

I hope this helps!
