Find the x and y intercepts of a line that is perpendicular to the line y = 9/8x + 1 and passes through the point (18, 8).

bobpursley,
perpendicular means the slope is the negative reciprocal...
y= 8/9 x + b is the general form, put in the point 18.8, and solve for b, and you have the equation.
Put in x=0, and you have the y intercept.
Put in y=0, and you have the x intercept.
