Find the equation of the line that goes through the points (4, –1) and (2, –5). use slope formula, equation, to find the slope of a line that passes through the points. m = use slope-intercept form, y = mx + b, to find the y-intercept (b) of the line. b = write the equation in slope-intercept form, y = mx + b.

The parabola x= √y-9 opens: a.)up b.)down c.)right d.)left

Hi, can anyone show me how to do this problem? 100 points for this. in advance
