What is the slope of the line?
I will mark the brainliest!

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.)

Match each inequality to the number line that represents its solution

Does anyone know how to solve and graph this: 4 + | a + 2 | < 7the only part i don't get is the "4 +"
