=Common Assessments= Exit Ticket Assessments (Examples) Teresa suggests: Use the problems from the parent guide as exit slip assessments.


 * 4.1**
 * Given y = 3x + 4; identify the rate of change and the y-intercept


 * 4.2**
 * Write an equation with zero slope, another equation with rate of change 3 and y-intercept 4, and last an equation with negative slope.
 * Match a graph with a table.
 * Given three different tables that are linear data, one with consecutive values, one without y-intercept, and one with non consecutive values, write the equation of line.


 * 4.3**
 * Ch3 Test Challenge problem; identify y-int and rate of change with different scale axes from 2nd quadrant


 * 4.4**
 * Write an equation of a line given a table of data. Extra points were given for each equation that was written.


 * Skipped 4.6 and 4.7**
