Determine if (2, 3) is a solution to the following equation
y = 5x - 1

Can (3,5 and square root 34) be sides on a right triangle?

Pls! does anybody know a shortcut for answering these types of questions in the future?

For the quadratic function [tex]y=(x+4)^2-1[/tex] , do the following: a) rewrite the function in the standard form, b) rewrite the function in intercept form, c) find the vertex, d) find the y-intercept, e) find the x-intercepts.
