1. Find the slope of the line passing through the points (7, –4) and (–6, –7).
 Slope = rise/run = (y2  y1)/(x2  x1) = (4  7)/(7  6) = (4 + 7)/(7 + 6) =
3/13
2. 2x + 7 = 1
Split into 2 equations and solve for x:
2x + 7 = 1 and 2x + 7 = 1
 7 7  7 7 subtract 7 on each side to get 2x by itself
__________ ____________
2x = 6 2x = 8
/2 /2 /2 /2 divide by 2 on each side to get x by itself
__________ ____________
x = 3 x = 4
x = 3, 4
