A line with a slope of -2 that goes through the point (1,-3) b. A line with a slope of zero that passes through (2,-1) c. A line with an undefined slope that passes through (-1,2) Answer by uma(370)   (Show Source): You can put this solution on YOUR website!a)Equation of a line with slope 'm' and through (x1,y1) is given by y-y1 = m(x-x1) ==> y -(-3) = (-2)(x-1) ==> y + 3 = -2x + 2 ==> y = -2x + 2 - 3 ==> y = -2x - 1 is the required equation. b) Slope = 0 and passes through (2,-1) ==> y - (-1) = 0(x-2) ==> y + 1 = 0 ==> y = -1 is the required equation. c) Slope = undefined and passes through (-1,2) ==> y - 2 = (1/0)(x-(-1))[undefined = 1/0] ==> 0(y-2) = 1(x+1) ==> 0 = x + 1 ==> x = -1 is the required equation. In the above graph, the red line represents (a) and green line represents (b).(c) is not shown on the graph, but it is a line parallel to y axis and through x = -1(left of y axis) Good Luck!!!
