The double number line shows that Jonah needs 28 seconds to fold 2 shirts.

There is a line with slope 1/a going through the point (a, a²). find the equation of the line perpendicular to this line at this point. (don’t let this problem intimidate you! solve the problem as you would if i’d given you specific values. just use variables instead.)

Which expression can be used to determine the slope of the line that passes through the points -6, three and one, -9
