10. Plans for a bridge are drawn on a coordinate grid. One girder of the bridge lies on the line y = –9x – 9. A perpendicular brace passes through the point (–1, 7). Write an equation of the line that contains the brace. y – 1 = –1/9(x + 7) x – 7 = –9(y + 1) y – 7 = 1/9(x + 1) y – 7 = –9(x + 1)

    ok so what we are going to do is find the inverse equation start by using the rule The gradient of the new line is -(1/grad of old line).
