Question 77961: Question#2 Find the equation in slope intercept form of the line that passes thru the points (-5,2) and (-4,1). Please help I cant figure it out. If you can break it down into steps that would be awesome. Thanks NR Answer by scott8148(6628) (Show Source):
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
