text: how do i find an equation when i have 1 coordinate pair and the slope? hi, i have a question on my homework, it says:  find an equation for the line through the given point with slope m.  (-4,1), m=-2  (6,10), m=0  i need help... what am i supposed to do? if the slope is zero, that means it's a horizontal line.  therefore, the equation for (6,10) is y=10.
