Answer:
1/2 a mile
Step-by-step explanation:
if she goes 1/4 mile in 1/2 hour than you have to multiply 1/2 by 2 so you do the same thing to 1/4 which equals 2/4 simplified equals 1/2 so your answer is 1/2 a mile.
- Slope-Intercept Form: y = mx + b, with m = slope and (0,b) as the y-intercept.
So starting with the y-intercept, the easiest method to find it is to convert this standard form equation to slope-intercept form. Firstly, add 5x to both sides:

Next, divide both sides by -4 and your slope-intercept form is 
Looking at this slope-intercept form, <u>the y-intercept is (0, -5/2).</u>
Now to find the x-intercept, just set the y-variable to zero and solve:

<u>Our x-intercept is (-2,0).</u>
Tbh i dont know i just need points to ask a question sorry :/
