Description : 9th grade, quadratic equations, and graphing calculators.. Is this a real thing?
Last Answer : answer:When I was in school, such calculators were banned, at least on tests. The point of the class was to learn to do it yourself to demonstrate understanding of the material. Oddly, most places that “require” TI calculators prohibit HP or Casio equivalents. Make of that what you will.

Description : Without using Pythagoras’ theorem, show that the points A (0, 4), B(1, 2) and C(3, 3) are the vertices of a right angle triangle. -Maths 9th
Last Answer : Slope (m) = \(rac{(y_2-y_1)}{(x_2-x_1)}\) = \(rac{6-2}{5-1}\) = \(rac{4}{4}\) = 1Also slope (m) = tan θ, where θ is the inclination of the line to the positive direction of the x-axis in the anticlockwise direction. tan θ = 1 ⇒ θ = tan –11 = 45º.
