Hi,
Using the standard slope-intercept form for an equation of a line y = mx + b
where m is the slope and b the y-intercept.
perpendicular to y= 2x-1 ( m = 2), contains (2,7)
New Line:
Note: negative reciprocal of 2
y = (-1/2)x + b
7 = (-1/2)·2 + b |Using ordered pair (x,y): (2,7) to solve for b
8 = b
y = (-1/2)x + 8
