Question 214303: I have a homework assignment and I need an example of one so I can answer the rest of the questions. Find the line passing through the following pairs of points?
(3, 11) (6, 20)
Can you please show me how to figure these kind of questions out. Thanks

You can put this solution on YOUR website!
first, find the slope (m) ___ m = (20 - 11) / (6 - 3) = 9 / 3 = 3

using the point-slope form, you can write the equation of the line ___ y - 11 = 3 (x - 3)

y - 11 = 3x - 9

y = 3x + 2 (this is the slope-intercept form : y = mx + b)

Find the equation of the line that passes through the two points (3,11) and (6,20)
Since you don't specify the form of equation you need, I'll assume that the "slope-intercept" form (y = mx+b) is acceptable.
Start by finding the slope (m) of the line using the two given points.
m+=+%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29 where:x%5B1%5D+=+3, y%5B1%5D+=+11, x%5B2%5D+=+6, and y%5B2%5D+=+20 Making the appropriate substitutions, we get:
m+=+%2820-11%29%2F%286-3%29
m+=+9%2F3
m+=+3
So you can start out with:
y+=+3x%2Bb To find the value of b, the y-intercept, substitute the x- and y-coordinates of either one of the two given points. Using the first point (3,11) we have:
11+=+3%283%29%2Bb
11+=+9%2Bb Subtract 9 from both sides.
2+=+b
The final equation is:
highlight%28y+=+3x%2B2%29
