2. Two sidewalks in a park are represented by lines on a coordinate grid. Two points on each of the lines are shown in the tables Sidewalk 1
x у
2 5
0 1

Sidewalk 2
х у
1 3
3 -3

(a) Write the equation for Sidewalk 1 in slope-intercept form.

(b) Write the equation for Sidewalk 2 in point-slope form and then convert to slope-intercept form.

(C) Is the system of equations consistent independent, coincident, or inconsistent? Explain.

(d) Use the substitution or elimination method to solve your system, and explain which one you picked. If the two sidewalks intersect, what are the coordinates of the point of intersection?

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
