Answer:
y = 4x - 15
Step-by-step explanation:
Find slope (m) using of the line that passes through (7, 13) and (4, 1).
Find y-intercept (b) by substituting x = 4, y = 1, and m = 4 in y = mx + b.
Thus:
1 = (4)(4) + b
1 = 16 + b
Subtract 16 from each side
-15 = b
b = -15
substitute m = 4, and b = -15 in y = mx + b, to get the equation.
The equation of the line would be:
✅ y = 4x + (-15)
y = 4x - 15
Given:
x = number of hours
y = total number of pages
70 = number of pages already read
30 =number of pages read per hour
y = 30x
70 = 30x
70/30 = 30x/30
2 1/3 = x
You read 70 pages within 2 hours and 20 minutes.
y = 30x
y = 30(3)
y = 90
An additional 90 pages have been read after another 3 hours.
Total pages read.
y = 30(2 1/3) = 70 pages
y = 30(3) =<u> 90 pages</u>
160 pages within 5 hours and 20 minutes.
