Answer:
E
Step-by-step explanation:
The number of pages in the book is actually irrelevant.
Franco reads 30 pages in 1 night. To find how many pages he reads in 7 nights, just multiply by 7.
30*7=210
Franco reads 210 pages in 7 nights.
Solving with Equivalent Ratios:
The ratio of pages he reads per night is 30:1. We need to figure out the ratio <em>x</em>:7, where the variable <em>x</em> is the number of pages he reads in 7 nights.
30:1=<em>x</em>:7
To find x we need to see the similarity between both ratios. This is found by dividing two of the equal sides, here it would be 7 and 1.
7/1=7
This means that the second ratio is 7 times the first ration. To find <em>x</em>, just multiply 30 by 7.
30*7=210
Franco reads 210 pages every 7 nights.

Answer:
y = 4x -14
Step-by-step explanation:
The required answer form is slope-intercept form, so we need the slope and the y-intercept of the line.
The slope equation is ...
m = (y2 -y1)/(x2 -x1)
m = (10 -2)/(6 -4) = 8/2 = 4
The y-intercept equation is ...
b = y - mx
b = 2 -4(4) = -14
The equation of the line is y = 4x -14.
