The graph below represents the number of books jaleel has read over the past x weeks. books read mc006-1.jpg which equation represents the graph?

I attached the graph related to the question


The equation is:
y = x + 3

Explanation:
The general form of the linear equation is:
y = mx + c
where m is the slope and c is the y-intercept

1- getting the slope:
To get the slope, we need two points. From the graph, we can use the points (1,4) and (2,5)
We can now get the slope as follows:
slope = 
slope = 
Therefore, the equation now became:
y = x \= c

2- getting the value of c:
c represents the y-intercept which is the value of y at x = 0
From the graph, we can find that at x = 0, y is equal to 3
This means that the y-intercept is 3 (c=3)

Based on the above, the equation is:
y = x + 3

Hope this helps :)

Iknow one of the answers is a and maybe b but not 100% sure about b
