Find the equation for a line that passes through the point (4,8)

Answer 1

there are an infinite number of lines that pass through the point (4,8)

a vertical line through that point is: x=4

a horizontal line through that point is y=8

a slanted line through that point is y-8 = m(x-4) where m= any real number= the slope of the line

if the slope is 1, a diagonal line upward sloping with an angle of 45 degrees with the x axis

then the line's equation is y= x +4

if the line through that point has slope =-1, it's a downward sloping line with equation y =-x +12
