Julia writes 2 fractions with the same denominator that have numerators 5 and 7. what could the denominator be if the sum is less than 1? equal to 1? greater than 1?

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.)

Choose the point slope form of the equation below that represents the like that passes through the points (-6,4) and (2, 0)

Ineed i been stuck on this question since yesterday
