No; their slopes are not equal.
To determine if two lines are perpendicular, we have to compare the slopes of the two lines. The first line, y = -x - 4, has a slope of -1. The second line, 5x + 5y = 20, can be rearranged to get the slope-intercept form: y = -x + 4, which has a slope of -1 as well. Since their slopes are equal, the lines are not perpendicular.
