Question 825820: a. Determine the equation of the line connecting the points (0,-1) and (2,3).
b. Will the line described by the equation in (a) intersect the line passing through the points (-2,4) and (-3,3)? Explain why or why not.

(0,-1) and (2,3)
Use the point-slope formula
= slope
= y-intercept
----------------------------
The line goes through ( 0,-1 )
which is the y-intercept, so
= ( change in y ) / ( change in x )
--------------
So, the equation is:
-------------------
(-2,4) and (-3,3)
If the slope of the other line is NOT
the same as this line, then they will intersect
This slope is different, so they will intersect
