Irfan is transferring the drawing of figure abcd to a coordinate plane. He plots point A at (-2, -1), and point B at (1,3) on a coordinate plane. Graph the ordered pairs that show points C and D, and then connect the points to form Irfan's figure.

Determine whether the graphs of y=8x+5 and -y=8x-5 are parallel, perpendicular, coincident, or none of these. a. coincident b. parallel c. perpendicular d. none of these

Worth 30 points! in this diagram, both polygons are regular. what is the value, in degrees, of the sum of the measures of angles abc and abd?

Which of these statements is correct? the system of linear equations 6x - 5y = 8 and 12x - 10y = 16 has no solution. the system of linear equations 7x + 2y = 6 and 14x + 4y = 16 has an infinite number of solutions. the system of linear equations 8x - 3y = 10 and 16x - 6y = 22 has no solution. the system of linear equations 9x + 6y = 14 and 18x + 12y = 26 has an infinite number of solutions.
