 Best Answer:<span>  </span><span>I'll make one up and explain how to do it. 

Lets say your two points are (2,6) and (-4,7) 

To start with you need to use the point-slope formula which is y2-y1/x2-x1 

Remember (x,y), Thus we have 

7-6/-4-2 = 1/-6; So out slope is -1/6 

Now lets use the following equation y = mx+b to solve for b which is the y-intercept. By substitution of either order pair we can solve for b 

6 = 2(-1/6)+b; distribute the 2 
6 = -2/6+b; add 2/6 to each side to isolate b 
6+2/6 = b; put 6 over 1 
6/1+2/6 = b; get a common denominator between 6/1 and 2/6 which is 6 
6(6/1)+2/6 = b ; distribute 
36/6+2/6 = b; add these up 
38/6 = b; reduce to lowest terms by dividing by 2 to each 
19/3 = b 

So our final equation is y = -1/6x+19/3 </span>

What is the least common denominator of<br> 1/3 and 5/9
crimeas [40]

Answer:

<h2>LCD = 9</h2>

Equivalent Fractions with the LCD

1/3 = 3/9

5/9 = 5/9

Solution:

Rewriting input as fractions if necessary:

1/3, 5/9

For the denominators (3, 9) the least common multiple (LCM) is 9.

LCM(3, 9)

Therefore, the least common denominator (LCD) is 9.

Calculations to rewrite the original inputs as equivalent fractions with the LCD:

1/3 = 1/3 × 3/3 = 3/9

5/9 = 5/9 × 1/1 = 5/9

Answer:

130

Step-by-step explanation:

The Honda will cost 24480 - 1400 = 23080

The Toyota will cost 25500 - 0.1 * 25500 = 25500 - 2550 = 22950.

So the Toyota will cost 130 less
