Question

Which answer is an equation in point-slope form for the given point and slope?

Point: (1,9); Slope: 5
A) y−1=5(x+9)
B) y−9=5(x−1)
C) y+9=5(x−1)
D) y−9=5(x+1)

Answer 1

Francine has just set up her Christmas tree. 40% of her ornaments are red. If she has 30 ornaments, then how many are red?

Explanation:

Answer 2

B
`(y-9)=5(x-1)`

Explanation:

Formula of straight line in Point slope form

`(y-y_1)=m(x-x_1)`

Here

`m=5 \ and \ (x_1, y_1)=(1, 9)`

therefore equation of line having slope 5 and passing through point )1, 9) is given as

`(y-9)=5(x-1)`
