Question

ffind the equation of the tangent to the parabola which is parallel to y+x=5

Answer 1

so what is the equation of the parabola..?

the line given is

y = -x + 5

so the slope is m = -1

so find the 1st derivative of the parabola. Let it equal -1. then solve for x. This will give the x, value of the point on the parabola.

Substitute the x value to get the corresponding y value so you have an ordered pair
(x, y)

you know m = -1

so use the point slope formula to find the equation of the tangent.

hope it helps
