So, we have the percentage she gets which is, 90% and the number of questions she answers correctly, which is 27
To find the number of questions in the exam, make an equation
(90% =

= 0.9)

=

cross multiply and equate them
90x = 27 x 100
90x = 2700
divide by 90 on either sides to isolate x in order to find the answer

90 and 90 cancels out
x = 30So your final answer will be,

Hi there! :)
Let’s solve this problem! :)
Remember, the y-intercept of a line is where the graph touches the y-axis.
Let’s look at our graph.
Also, remember that y-intercepts always have an x-coordinate of 0.
So, the y-intercept of the line is
(0, 2)
We can also write this as 2.
Therefore, the y-intercept of this line is 2. (Answer)
Hope it helps. Enjoy your day/night :)
