What is an equation of the line that passes through the points (4, -1)(4,−1) and (-8, -7)(−8,−7)?

Which of the following equations is of the parabola whose vertex is at (4, 3), axis of symmetry parallel to the y-axis and focus at (4, -3)? a.) y+3=1/24 (x+4)^2 b.)y-3=-1/24 (x-4)^2 c.)x-4=-1/24 (y-3)^2

Write the equation in logarithmic form e^x=403.429

Which one is the correct answer, and why?
