Chapter 4: Q7. (page 279)

What is the equation of the line graphed below?

Express your answer in point-slope form using the point 鈭�8,3.

Short Answer

Expert verified

The required equation is represented byy=鈭�14x+1.

Step by step solution

01

Step 1. Determine the formula that can be used.

The standard form associated with a line that is having travel through points which are two in the county鈭�y1=y2鈭�y1x2鈭�x1x鈭�x1 can be used to calculate the required equation.

02

Step 2. Take the help of the obtained method. 

Take the help of obtained standard form represented by y鈭�y1=y2鈭�y1x2鈭�x1x鈭�x1in which the required values can be filled by using the provided point and the point which represents the traveling of the line through the horizontal axis 4,0as they are in the form of x1,y1,x2,y2.

y鈭�0=3鈭�0鈭�8鈭�4x鈭�4y=鈭�14x+1

03

Step 3. Write the conclusion. 

The obtained equation isy=鈭�14x+1 so is the required equation.
