Question

Write an equation in point-slope form of the line having the given slope that contains the given point.

m = 5/6, (30, 12)

A) y = 5/6 x - 37
B) y - 30 = 5/6 (x - 12)
C) y + 12 = 5/6 (x - 30)
D) y - 12 = 5/6 (x - 30)

Answer 1

c

Explanation:

It would be c because you would add subtract 30 - x which equals 30x then you would divided 5 / 6 which equals 0.12 then you would add y plus some number which equals 12y then you would add 12y+12=24y=24y / 2=12 thenyou have 30x,12y.

Answer 2

D

Explanation:

A might be right for the wrong linear equation type. It could be describing a y intercept slope line. So even if it is right, it is not the answer. Actually the answer to A should be y = (5/6)x - 13

The general formula for the answer you want is

Givens

y -y1 = m(x - x1)

x1 = 30

y1 = 12

m = 5/6

Solution

y - 12 = (5/6)(x - 30)

That makes the answer D
