Question 349677: Consider two equations in point slope form. y-1=x-2 and y+5=x+4. Do the equations represents the same line? explain. write and equation in slope-intercept form for a line that is perpendicular to a line for one of the given equations. how many equations can be written for line that are perpendicular to a line for one of the given equations? explain. Please answer. i don't get it

You can put this solution on YOUR website!
+y-1=x-2
1+=+x+-+y
y%2B5=x%2B4
1+=+x+-+y
SO the equations are the same line.
Put it in slope intecept
1+=+x+-+y
y+=+x+-+1 is in the form (y = mx + b) when m=1 and b = -1
To find the line perpendicular, it needs a slope that is the negative reciprocal of the given line.
y+=+-x+-+1
There are an infinite number of lines perpendicalar to the given line (all you need to do so show that is leave the slope as is and chang ethe value of b (in this case -1) to any number.
