Determine the equation of the line passing through the points (−1,1) and (1,7).
1 answer:
Answer:
Step-by-step explanation:
To make things easier, let's first find the equation in slope-intercept form ( where m is the slope and b is the y-intercept.
1. Find the slope:
2. Find the y-intercept by plugging in (-1,1) into the equation
so = 4
3. Therefore the equation of the line in slope-intercept form is
4. To convert slope-intercept form into standard form, let's move the 3x over to the other side and divide by -1 to get rid of the negative.
Our result is .

To start this problem, let's first assign a variable for the missing, consecutive odd numbers. Since they are consecutive and odd, we add two.
<u>Proof:</u> <em>3-1=2, 5-3=2</em>
The first, consecutive, odd number:
The second, consecutive, odd number:
The third, consecutive, odd number:
The fourth, consecutive, odd number:
The sum of the values are equal to 3 times the sum of the first two numbers, of which this is equal to 35 less than the fourth number. Let's create an equation to simplify this:
Complete the operations inside the parenthesis:
Distribute the parenthesis (utilizing the distributive property)
Simplify both sides:
Add -6 and -x to both sides of the equation:
Divide both sides of the equation by 5:
If is equal to -7:
The four numbers are:
