look at the sum of two rational numbers let's say they are two rational numbers x and y. because they're rational, they can be written as a ratio of integers. let x = a/b and y =c/d where a b c and d are integers and b and d do not equal 0. the process for finding the sum x +y in terms x + y are shown. based on this sum and using the closure property of integers, what inclusion can you make about the sum of two rational numbers?explain your answer

A, b, c, and d have the coordinates (-8, 1), (-2, 4), (-3, -1), and (-6, 5), respectively. which sentence about the points is true? a. a, b, c, and d lie on the same line. b. and are perpendicular lines. c. and are parallel lines. d. and are intersecting lines but are not perpendicular. e. and are parallel lines.

Suppose you are going to graph the data in the table. minutes temperature (°c) 0 -2 1 1 2 3 3 4 4 5 5 -4 6 2 7 -3 what data should be represented on each axis, and what should the axis increments be? x-axis: minutes in increments of 1; y-axis: temperature in increments of 5 x-axis: temperature in increments of 5; y-axis: minutes in increments of 1 x-axis: minutes in increments of 1; y-axis: temperature in increments of 1 x-axis: temperature in increments of 1; y-axis: minutes in increments of 5

Write the point-slope form of the line passing through (2, -12) and parallel to y=3x.
