Step-by-step explanation:
Answer:
Slope = 2/3 Y intercept +3
Step-by-step explanation:
Plot the y-intercept (0,+3) in the xy axis. Remember, this point always lies on the vertical axis y.
Starting from the y-intercept, find another point using the slope. Slope contains the direction how you go from one point to another.
The numerator tells you how much steps to go up or down (rise) while the denominator tells you how many units to move left or right (run).
Connect the two points generated by the y-intercept and the slope using a straight edge (ruler) to reveal the graph of the line.
Divide 56 by 2 and you get 28,therefore 28 chips per box
In this case, 7 is being added to the odometer which already reads 78. If you add 7 to 78, you get 85. Meaning y = 85!
