The equation that represents the relationship between the number of days and the number of pages  Lila reads is y = 42x

If Lila read 84 pages in 2 days and 210 pages in 5 days, the number of pages "y" and the number of days "x" can be express in coordinate form as shown:

(2, 84) and (5, 210)

To get the required equation, we will find the equation of the line passing through the coordinate points as shown:

y = mx + b

m is the slope

b is the y-intercept;

Get the slope

[tex]m =\frac{210-84}{5-2}\\m=\frac{126}{3}\\m=42\\[/tex]

Get the y-intercept:

84 = 42(2) + b

84 = 84 + b

b =0

Get the required equation:

Recall that y = mx+ b

y = 42x + 0

y = 42x

Hence the equation that represents the relationship between the number of days and the number of pages  Lila reads is y = 42x
