Plans for a bridge are drawn on a coordinate grid. One girder of the bridge lies on the line y=3x - 5. A parallel brace passes through the point (5, -7). Write an equation of the line that contains the brace

Triangle xyz, with vertices x(-2, 0), y(-2, -1), and z(-5, -2), undergoes a transformation to form triangle x? y? z? , with vertices x? (4, -2), y? (4, -3), and z? (1, -4). the type of transformation that triangle xyz undergoes is a . triangle x? y? z? then undergoes a transformation to form triangle x? y? z? , with vertices x? (4, 2), y? (4, 3), and z? (1, 4). the type of transformation that triangle x? y? z? undergoes is a .

Ireally don't understand this, i'm really an idiot but i want to know how to figure this out. !

Can random samples and proportional reasoning be used to determine precise information about a population? explain
