Question

which of the following is a point slope equation of a line with the point (1, 8) and a slope of -5? a. y +8=-5(x+1) b. y- 5 = -5(x-8) c. y+ 5= -5(x+8) d. y-8=-5(x-1)

Answer 1

Option D.
`y-8=-5(x-1)`

Explanation:

we know that

The equation of a line into point slope form is equal to

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

we have

`(x1,y1)=(1,8)`

`m=-5`

substitute

`y-8=-5(x-1)`
