<span>When interpreting graphs of real world situations, the slope of each part tell you the average rate of change (increase or decrease) of the dependent variable with respect to the independent variable. This is, how much the dependent variable increased (or decrease) per each unit the independent varaible increased, in average.
slope = change in independent variable / change in dependent variable
slope = Δy / Δx</span>
Answer:
x=2 and y=5
Step-by-step explanation:
Steps:
I will solve your system by substitution.
x=y−3;2x+y=9
Step: Solve x = y − 3 for x:
Step: Substitute y − 3 for x in 2x + y = 9:
2x+y=9
2(y−3)+y=9
3y−6=9(Simplify both sides of the equation)
3y−6+6=9+6(Add 6 to both sides)
3y=15
3y/3=15/3 (Divide both sides by 3)
y=5
Step: Substitute 5 for y in x = y − 3 :
x=y−3
x=5−3
x=2(Simplify both sides of the equation)
Answer:
x=2 and y=5
So we know d. is out and that's all I got help wise sorry its not much..:)
