#color(magenta)(y = -1 * x -1 " is the slope-intercept form of the equation"#

Given line ; # x + y = 13#

#y = -1 * x + 13#

#:. "Slope " = m = -1#

Equation of the parallel line passing through "#(-8,7)# is

#y - y_1 = m * (x - x_1)#

#y - 7 = -1 * (x + 8)#

#color(magenta)(y = -1 * x -1 " is the slope-intercept form of the equation"#
