Question 1062200: Write the point slope form of the equation of the line that passes through the points (-3,5) and (-1,4) Found 2 solutions by Alan3354, Edwin McCravy:Answer by Alan3354(69443) (Show Source): You can put this solution on YOUR website! Same problem, different numbers.
=============================
Write the point slope form of the equation of the line that passes through the points (5,-9) and (-6,1)
---
slope = m = (1--9)/(-6-5) = 10/-11 = -10/11
-------------------
Form:: y = mx + b
Solve for "b"::
-9 = (-10/11)5 + b
-------
-9 + (50/11) = b
----
-99/11 + 50/11 = -49/11
-----
Equation:
y = (-10/11)x - (49/11)
-------------------

line that passes through the points (-3,5) and (-1,4)
Let's plot the points (-3,5) and (-1,4), and draw a line
through them (in green):
Now we use the slope formula:
Now use the point-slope form:
That's the point slope form. But it can be simplified
to the slope-intercept form y = mx+b
