Let x represent the number of minutes and y the cost. Then
y - 0.85 = (1.10 - 0.85)/(10 - 5) (x - 5)
y - 0.85 = 0.25/5 (x - 5) = 1/20 (x - 5) = 1/20 x - 1/4
y = 0.05x - 0.25 + 0.85 = 0.05x + 0.6
y = 0.05x + 0.6
The cost of 25 minutes = 0.05(25) + 0.6 = 1.25 + 0.6 = $1.85
Answer:
y = 25 + 5x
Step-by-step explanation:
Since the cost of Twitch is $25 no matter what, that will be our y-intercept (essentially when no other subscriptions are bought). Since with every purchase x we make, we spend an additional $5, the slope of the line (x coefficient) will be 5.

Answer:
see the explanation
Step-by-step explanation:
we know that
point B(-6, 1) is translated to B'(-3,-2)
step 1
The rule of the translation is
(x,y) -------> (x+a,y+b)
substitute
B(-6,1) -------> B'(-3,-2)
step 2
Write the equations
-6+a=-3
-2=1+b
step 3
Solve each equation
-6+a=-3 ------> a=-3+6 -----> a=3
-2=1+b ------> b=-2-1 ------> b=-3
step 4
Write the rule of translation
(x,y) -------> (x+3,y-3)
That means ------> The translation is 3 units at right and 3 units down
