You can put this solution on YOUR website!
first, find the slope (m)---divide the change in y (rise) by the change in x (run)--- m=(1-2)/(-4-(-5))...m=-1/1...m=-1

slope-intercept form is y=mx+b; where m is the slope and b is the y-intercept (where the graph crosses the y-axis)

knowing the slope (-1), you can plug in the x and y values from one of the points to find b...2=(-1)(-5)+b...2=5+b...b=-3

so the equation is y=(-1)x+(-3)...or y=-x-3
