What is the graph of y=2x+3? And solve the one on the right

Let's Graph the line ~

first find the acceptable ordered pairs for the equation.

Like ~

when x = 0, value of y is ~

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

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

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.

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 ~

Rearrange it, we will get ~

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

the answer to your question a or b but i am pretty sure it is b. i hope this : )
