Example Question #771 : Ged Math

Find the equation of the line the passes through (3,4) with a slope of 2

Possible Answers:

Correct answer:

Explanation:

Recall our point-slope form

Here  and  and 

So, plugging those in gives us

Lets distribute that 2

and add 4 to both sides

And simplify

Example Question #771 : Ged Math

Which of the following is an example of an equation of a line written in standard form?

Possible Answers:

Correct answer:

Explanation:

The standard form of a line is , where all constants are integers, i.e. whole numbers.

Therefore, the equation written in standard form is .

Example Question #772 : Ged Math

Line

Refer to the above red line. What is its equation in standard form?

Possible Answers:

Correct answer:

Explanation:

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

Given two points, , the slope can be calculated using the following formula:

Set :

Second, we note that the -intercept is the point 

Therefore, in the slope-intercept form of a line, we can set  and :

Since we are looking for standard form - that is,  - we do the following:

or
