Originally posted by Drew LUse the equation y = -3/4x + c Plug in one of the two coordinate pairs for x and y. If you use (-2, 1) then 1 = (-3/4)*-2 + c Then solve for c.
So, Im taking caculus this year and its day two and I already can't remember formulas of the past.
Write a general linear equation for the line through the two points. [In this book a general linear equation is ax + by = c rather than ax + by + c = 0]
points : (-2, 1), (2, -2)
therefore : m = -3/4 so y = -3/4x but how to find c? [y intercept]
Thanks for the help!

We get enough of these that we should start an "I need help with my homework" forum group.
