Question

Find the distance between the line y=4x-1 and the point (4,15).

Answer 1

create a function that gives the equation for the distance between these two points, and either take it's derivative and set it to zero, or complete the square to find the vertex of the quadratic

Answer 2

Huh? Sorry I'm terrible at all this.

Answer 3

Create a function using pythagorean theorem, draw the graph and the point and it will make sense

Answer 4

Okay. Thanks!

Answer 5

The distance from the line y=4x-1 to the point will be a perpendicular line to the point 4,15. This line will have a slope of -1/4 and will pass through point 4, 15.
