To find the slope, m, of a line that passes through the two given points, (x1, y1) and (x2, y2), use the formula:

In your problem, the given points are: (x1, y1) is (1, 7) and (x2, y2) is (3, 3).
If you now make the appropriate substitutions into the slope formula you will have found the slope of the line.
Simplify this to get:

Hi DB
To find the equation of a line we need a point and a slope. We have a point, but no slope. We can find a slope (m)if we're given 2 points by using the slope formula:
Our (x1,y1)=(1,7) and (x2,y2)=(3,3)

I should have stopped here. You only asked for the slope. I got carried away and gave you the equation of a line. You'll be doing that soon if you aren't already, so I'll leave it here.
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Now we have a point (x1,y1)=(1,7) and a slope m=-2, so we can find the equation of the line using the point slope formula: .

<----slope intercept form

Happy Calculating!!!
