the graph of a line passes through the points (0,-2) and (6,0). what is the equation of the line?
Simple, using y1-y2 and x1-x2 method to find the slope, take (0,-2) and (6,0) and, -2-0 over (-2-0/0-6) 0-6 making it -2/-6=3 Thus, your slope is 3. But you're still not done, use slope and plug it into any of the points. Using (0,-2) An equation in slope-intercept form is y=mx+b Thus, -2=3(0)+b -2=0+b -2=b Thus, your equation is y=3x-2.
