Functions: Graphing Functions Practice MCQ

Question Statement:

Refer to the line in the above diagram. It we were to continue to draw it so that it intersects the y-axis, where would its y-intercept be?

(0, - 1 \frac{2}{5})

(0, - 1)

(0, - 1 \frac{2}{3})

(0, - 1 \frac{1}{3})

(0, - 1 \frac{3}{5})

Explanation:

Correct Answer: D

First, we need to find the slope of the line.

In order to move from the lower left point to the upper right point, it is necessary to move up five units and right three units. This is a rise of 5 and a run of 3. makes the slope of the line shown $\frac{5}{3}$ .

We can use this to find the y-intercept (0,b) using the slope formula as follows:

The lower left point has coordinates (2,2). Therefore, we can set up and solve for b in this slope formula, setting

$x_{1} = y_{1} = 2, x_{2} = 0, y_{2} = b, m = \frac{5}{3}$

You are taking Aptitude Test No. 1

Each aptitude test is comprised of 10 except the last test which might have fewer than 10 in some topics.

You are at question (MCQ) number 6 and Test Number 1 of Functions: Graphing Functions. To deal with Functions questions, you must take lesson on the subject. In case of science and Art subjects revise your text books and in case of general aptitude topics take lessons from the topic page.

The question:

( 0 , − 1 2 5 ) ,

(0, - 1)

(0, - 1 \frac{2}{3})

(0, - 1 \frac{1}{3})

can be solved with the concepts and understanding of Functions.
