Estimation  A train leaves the station at time x=0. Traveling at a constant speed, the train travels 334 km in 3.3 h. Round to the nearest 10 km and the nearest whole hour. Then represent the distance, y, the train travels in x hours using a table, an equation, and a graph.

Agiven line has the equation 2x + 12y = −1. what is the equation, in slope-intercept form, of the line that is perpendicular to the given line and passes through the point (0, 9)? y = ( )x + 9

What expression is equivalent to (2x-1)(x-3)?
