Step-by-step explanation:
There are several which in which we can approach this question:
We can do this question using direct proportion.

Hi there! :)
Answer:
Given the information, we can write an equation in slope-intercept form
(y = mx + b) to graph the line:
Plug in the slope for 'm', the y-coordinate of the point given for 'y', and the
x-coordinate given for 'x':
-4 = -2/3(-7) + b
-4 = 14/3 + b
Solve for b:
-12/3 = 14/3 + b
-12/3 - 14/3 = b
-26/3 = b
Therefore, the equation of the line is y = -2/3x - 26/3 (Graphed below)
Some points on the line include:
(-7, -4)
(-4, -6)
(0, -26/3)
(2, -10)
(5, -12)
Step-by-step explanation:
3 hours =5 pages
8 hours =x
Cross multiplying
3x=5×8
3x=40
Dividing both sides by 3
3x/3=40/3
x=13.33
To the nearest whole number Henry will write 13 pages in 8 hours
