13. When a linear function is graphed, it passes through the points (-1, 1), (1,5), and (3,9).
Part A: What is the rate of change for the function?
Part B: Does the equation y =
2x + 3 represent the function? Explain your reasoning.
Your answer
14.

There is an entrance to the computer room at point e which lies on ab and is 5 feet from point a. plot point e on the coordinate plane. find the distance from the entrance at point e to the printer at point e

In each of the cases that follow, the magnitude of a vector is given along with the counterclockwise angle it makes with the +x axis. use trigonometry to find the x and y components of the vector. also, sketch each vector approximately to scale to see if your calculated answers seem reasonable. (a) 50.0 n at 60.0°, (b) 75 m/ s at 5π/ 6 rad, (c) 254 lb at 325°, (d) 69 km at 1.1π rad.

Ade and abc are similar. which best explains why the slope of the line between points a and d is the same as the slope between points a and b?
