Answer:
m=(y-b)/x
Step-by-step explanation:
In this equation if we want to find an equivalent equation for any of the letters what we need is to left that letter in one side and all the others letters in the other side
At the begining whe have y=mx+b and we need the m alone in one side
y-b=mx
(y-b)/x=m
Convert 7/8 and 4/5 into common denominators using 40; 28/40 and 32/40, multiply those to get 22.4. Divide 7 by 20 to get 0.35. Divide 22.4 by 0.35 for an end quotient of 64.
If you distribute -4 through (5k-7), it equals -20k + 28. Then put on the other -2k on that side of the equals sign and you should have -22k + 28 = -2(9k+5) Then you need to distribute -2 through (9k+5) which equals -18k - 10. You then should have -22k+28=-18k-10. Add 22k to both sides to cancel it out, then you should have 28=4k-10. Add 10 to both sides to get the 4k by itself, which will be 38=4k, then divide both sides by 4 to get k by itself. 38/4 = 19/2. k = 19/2
