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.
line that passes through the point (2,4) and has the indicated slope m = -1.
Line
y = (-1)x + b
4 = (-1)·2 + b |Using ordered pair (x,y):(2,4) to solve for b
6 = b
y = -x + 6 or x + y = 6
