The linear equation that represents the <u>number of tiles in figure x</u> is given by:
---------------------
A linear equation has the format:
In which:
- m is the slope, that is, the rate of change.
- b is the y-intercept, that is, the value of y when x = 0.
---------------------
- Figure 0 has 5 tiles, that is, when
, thus 
- Seven new tiles in each figure, that is, a rate of change of 7, thus
The number of tiles in figure x is given by:

In solving equations, each must have vales of x and y. X is any number and Y is the output of any number. If you substitute x for a number, you can solve the equation for y.
Answer:
y = 4x – 10
Step-by-step explanation:
slope formula: 
point-slope formula: 
- Use slope formula and plug in your numbers:
- Solve for slope
- Use the point-slope formula to solve for the equation:
- Solve and find equation:
Note: When given two points you only need to pick one for the point-slope formula! Best to choose the positive one so you don't have to deal with the negatives!

Given,
CP of cosmetics = Rs 360 per dozen
SP of a pair of cosmetics = Rs 80
To find,
The gain percent
Solution,
1 dozen = 12 items
CP of 1 cosmetic = 360/12 = Rs 30
SP of 1 cosmetic = 80/2 = Rs 40
Profit = SP-CP
= Rs 40 - Rs 30
= Rs 10
Profit percentage is given by :
So, the profit percentage is 33.34%.
