The slope is -7/4
Step-by-step explanation:
∵ 7x + 4y = 10
∵ y = mx + c ⇒ where m is the slope of the line
∴ Re-arrange the equation
∴ 4y = 10 - 7x ⇒ ÷4
∴ y = 10/4 - (7/4) x
∴ y = 5/2 - (7/4) x
∴ The slope is -7/4

=========================================================
Explanation:
I'm assuming letters can repeat.
There are 26 letters in the English alphabet.
There are,
- A = 26^4 = 456,976 strings of length four
- B = 26^3 = 17,576 strings of length three
- C = 26^2 = 676 strings of length two
- D = 26 strings of length one
Overall, there are A+B+C+D = 456,976+17,576+676+26 = 475,254 strings of length four or less.
