Answer: <em>2x + y = 10</em>
Step-by-step explanation: When we're given a point and a slope, we can use the point-slope formula to write the equation of a line.
The point-slope formula is y - y₁ = m(x - x₁).
Now we can substitute our point and our slope into the formula.
y - 4 = -2(x - 3)
~distribute
y - 4 = -2x + 6
~isolate y
y = -2x + 10
~put into standard form
2x + y = 10

Answer:
300 minutes
Step-by-step explanation:
Let
x----> the numbers of minutes used
y ---> the cost per month
we know that
<em>First cell phone plan</em>
y=0.15x+20 ---> equation A
<em>Second cell phone plan</em>
y=0.10x+35 ---> equation B
equate the equation A and equation B
0.15x+20=0.10x+35
Solve for x
0.15x-0.10x=35-20
0.05x=15
x=15/0.05
x= 300 minutes
Find the cost y
y=0.15(300)+20 =$65
That means
For x=300 minutes
The cost for both calling plans is y=$65
