Sagot: #color (magenta) (y = -1 * x -1 "ang slope-intercept form ng equation" # Paliwanag: Given line; # x + y = 13 # #y = -1 * x + 13 # #:. "Slope" = m = -1 # Ang equation ng parallel line na dumadaan sa "#(-8,7)# ay #y - y_1 = m * (x - x_1) # #y - 7 = -1 * (x + 8) # #color (magenta) (y = -1 * x -1 "ang slope-intercept form ng equation" # graph {-x -1 -10, 10, -5, 5}
