What's the distance between 3 1/4 and 6 1/2?

Use the knowledge of x- and y- intercepts to choose the correct graph of the equation 3x+6y=6

What are the coordinates of the midpoint of ab? ,1/2) /2,-1) ,-3/2) /2,-2)

Evaluate the discriminant of each equation. tell how many solutions each equation has and whether the solutions are real or imaginary. x^2 - 4x - 5 = 0
