Answer:

Step-by-step explanation:
first find the slope using the above points then use the slope formula to calculate the slope

substitute ⅔ for m and one of the above points into the y-intercept form of the equation for a line and solve for b

substitute the slope and the value for b into the equation to get the answer

About miles.
Subtract the flat rate of 1.75 from the spending limit of 10$ which leaves you with 8.25 then divide the rest of your spending money (8.25$) into your rate per mile (0.65) , so essentially , 8.25 / 0.65 which leaves you with the answer of ;
12 miles.
Answer: x < 30
Step-by-step explanation:
Let the cost of a jean be x
cost of a shirt = $25
cost of 3 jeans = 3x
since he wants to spend less than $115 , this means that
3x + 25 < 115
3x < 115 - 25
3x < 90
x < 30
