<span>The three equations can be written as 1) y = 2x - 5 ; 2) y = 2x - 3 and ;3) y = 2x + 5. Now, the slope can be found by slop intercept form of linear equation i.e. y = mx+b where m is the slope. From the above equations, we can see that all the the three have the same slope i.e. m = 2.</span>
Jessica:
2 minutes = 60 jumping jacks
1 minute = 30 jumping jacks
Dale:
5 minutes = 150 jumping jacks
1 minute = 30 jumping jacks
Ans: Yes, both their rates are the same. They both jump at 30/min.
Each game costs 1.25 and each ride costs 3.75
Step-by-step explanation:
Let,
Cost of each game = x
Cost of each ride = y
According to given statement;
5x+6y=28.75 Eqn 1
4x+3y=16.25 Eqn 2
Multiplying Eqn 2 by 2

Subtracting Eqn 1 from Eqn 3

Dividing both sides by 3

Putting x=1.25 in Eqn 1

Dividing both sides by 6

Each game costs 1.25 and each ride costs 3.75
