This figure shows quadrilateral ABCD. The two diagonals of ABCD, BD and AC, are perpendicular to one another, and BC = DC. which theorem of triangle congruency can be used to proved that BEC = DEC

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.

Find the solution(s) to the system of equations. select all that apply y=x^2-1 y=2x-2

The approximate line of best fit for the given data points, y = −2x − 2, is shown on the graph.which is the residual value when x = –2? a)–2 b)–1 c)1 d)2
