Aline has a slope of m=12 and the point (-2,8) lies on the line. which of the following represent the line? select two answers.
a. y=12x-16
b.y=12x+32
c. y-8=12(x+2)
d. y+8=12(x-2)

b. y=12x+32, c. y-8=12(x+2)

Step-by-step explanation:

point -slope form equation

(y-y1) = m(x-x1)

(y - 8) = 12(x + 2) point slope form

y - 8 = 12x +24

y = 12x + 32 slope intercept form

225

Step-by-step explanation:

The sum of this series is given by the formula:

Where

S_n is the sum

a is the first term (we get this by plugging in n = 1 into "2n-1", we have 2(1) - 1 = 1)

n is the number of terms (the sum is defined for n = 1 to n = 15, so 15 terms)

d is the common different (the difference is successive terms. Here, 2nd term would be 2(2) - 1 = 3, and first term was 1, so d = 3 -1 = 2)

plugging in the info, we will get the sum:

The sum is 225
