What is the length of the line 5x plus 10 -y equals 0 that spans the parabola y equals x squared plus 4 showing work and answer to the nearest integer?
If: y = x^2 +4 and 5x+10-y = 0 or y = 5x+10
Then: x^2 +4 = 5x +10 or x^2-5x-6 = 0
Solving the above quadratic equation: x = -1 or x = 6
By substitution end points of the line are at: (6, 40) and (-1, 5)
Length of line is the square root of: (-1-6)^2 plus (5-40)^2 = 36 rounded

What is the parabola?
A parabola is a type of graph that is not linear, and mostly curved. A parabola has the "x squared" sign in it's equation. A parabola is not only curved, but all the symmetrical. The symmetrical point, the middle of the parabola is called the vertex. You can graph this graph with the vertex, x-intercepts and a y-intercept. A parabola that has a positive x squared would be a smile parabola, and the one with the negative x squared would be a frown parabola. Also, there are the parabolas that are not up or down, but sideways Those parabolas have x=y squared, instead of y = x squared.
