What is an equation of the line that is perpendicular to y - 3 = -4(x + 2) and passes throughthe point (-5, 7)

When you answer this can you explain

Someone answer asap for ! a ball is rolled down a ramp. the height, f(x), in meters, of the ball x seconds after it is released is modeled by the function f(x) = x²- 10x + 25 for all values of x from 0 to 5. which statement about the ball is true? a. the maximum height of the ball is 5 meters b. the height of the ball increases from 0 to 5 meters above the ground. c. the ball has traveled 5 meters when it reaches the bottom of the ramp. d. the ball has been traveling for 5 seconds when it reaches the bottom of the ramp

Determine if the equation defines y as a function of x: 2xy = 1. yes o no
