Answer:
y = 2x + 6
Step-by-step explanation:
slope-intercept form => y = mx + b
substitute two of the (x, y) into the equations: y = mx + b to solve for m and b
=> 0 = -3m + b, 6 = 0m + b
6 = 0m + b => b = 6
substitute b = 6 into 0 = -3m + b to solve for m:
=> 0 = -3m + 6 => -3m = -6 => m = 2
plug in b = 6 and m = 2 into the equation y = mx + b:
=> y = 2x + 6
Answer: Company A would be a better deal for number of minutes over 200
Step-by-step explanation:
Let x represent the number of minutes that you would use with either company A or company B.
Company A has a monthly charge of $10 plus 5¢ a minute for each minute of long distance calls. It means that the cost of x minutes of long distance call is
10 + 0.05x
Company B has a monthly charge of $8 plus 6¢ a minute for long distance calls. It means that the cost of x minutes of long distance call is 10 + 0.05x
8 + 0.06x
For Company A to be a better deal, it means that
10 + 0.05x < 8 + 0.06x
10 - 8 < 0.06x - 0.05x
2 < 0.01x
0.01x > 2
x > 2/0.01
x > 200
