Write equations for each line given the following points. Remember, you must first find the slope and then determine the y-intercept, then write out the equation in slope-intercept form. Remember if the y-intercept b is zero, then there is no need to put it there, and if the slope is 1, then you only need to write x, not 1x. 11. (-5, -2) and (-1, -6)
