Step-by-step explanation:
subtrat 14 and 2 1/3 to get b
Hello, I will try to help you as best as I can. Sorry if this is wrong. y = 0.8x +12
parallel line means it has similar gradient m= 0.8
Y = MX + C
just substitute the coordinate (-5,8) to find the variable c
8 = 0.8(-5) + C
C = 12
our answer is y = 0.8x + 12

-5 is the intercept since y=mx+b, b being the intercept.
the slope will be -6. the -3 -3 will be equal to -6
Answer: If the initial term of an arithmetic sequence is a 1 and the common difference of successive members is d, then the nth term of the sequence is given by: a n = a 1 + (n - 1)d The sum of the first n terms S n of an arithmetic sequence is calculated by the following formula: S n = n (a 1 + a n)/2 = n [2a 1 + (n - 1)d]/2
