Use the system 4x -2y=21, y - 2x =10. Write each equation in slope intercept form. Compare the slopes and y-intercepts. Make a conjecture about the graph and the solution of the system.

Point a is located at (0, 4), and point c is located at (−3, 5). find the x value for the point b that is located one fourth the distance from point a to point c. −0.25 −0.5 −0.75 −1

Which undefined geometric term is described as a location on a coordinate plane that is designed by an ordered pair (x, y) ?

Two planes leave an airport at the same time, one flying east, the other flying west. the eastbound plane travels 20 mph slower. they are 1600 mi apart after 2 hr. find the speed of each plane.
