Answer:
28x + 54 = 379 is what I came up with, though it would help to see the choises you have to select from if there are any.
Step-by-step explanation:
28 = the pages she reads in 1 hours.
x = how many hours it would take to finish the book.

Answer:
(0, -6)
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
<em>m</em> - slope
<em>b</em> - y-intercept
Step 1: Write standard form
3x - 7y = 42
Step 2: Rewrite in slope-intercept form
- Subtract 3x on both sides: -7y = 42 - 3x
- Divide both sides by -7: y = -6 + 3/7x
- Rewrite: y = 3/7x - 6
Step 3: Find y-intercept
<em>b</em> = -6
Christy's average mph is 48 because 132 divided by 2.75 = 48
