Let w=23 . what is the value of w + 45 ?

Which of the following equations is of the parabola whose vertex is at (2, 3), axis of symmetry parallel to the y-axis and p = 4? a.)y-3 = 1/16 (x-2)^2 b.)y+3 = -1/16 (x+2)^2 c.)x-2 = 1/16 (y-3)^2

Find the slope and the y-intercept if there's one and the equation of the line given these two points( 3, 2) and( 3, -4)
