Question ~ 1

Let's Graph the line ~

first find the acceptable ordered pairs for the equation.

Like ~

when x = 0, value of y is ~

  • [tex] \sf y = (2 \times 0) + 3[/tex]

  • [tex] \sf y = 3[/tex]

So, first ordered pair is ~ (0 , 3)

Second one, when x = 3, value of y is ~

  • [tex] \sf \: y = (2 \times 3) + 3[/tex]

  • [tex] \sf \: y = 6 + 3[/tex]

  • [tex] \sf y = 9 [/tex]

The other ordered pair is (3 , 9)

Now, mark the points on graph and join the points, the line joining the points will be the required line.

Question ~ 2

The number of pages he reads everyday is 30

The number of days he read the book = x

Let the number of pages left be y

now, according to given information, we can interpret the equation as ~

  • [tex] \sf y = 450 - 30x [/tex]

Rearrange it, we will get ~

  • [tex] \sf y = - 30x + 450 [/tex]

Here, the slope is -30, and y - intercept is 450
