Question

Choose the equation below that represents the line passing through the point (-3,-1) with a slope of 4.

A) y = 4x - 11
B) y = 4x + 11
C) y = 4x + 7
D) y = 4x - 7

Answer 1

The answer is the option B

`y=4x+11`

Explanation:

we know that

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

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

in this problem we have

`m=4`

`point(-3,-1)`

substitute

`y-(-1)=4(x-(-3))`

`y+1=4(x+3)` ---> equation of the line into slope point form

isolate the variable y

`y=4x+12-1`

`y=4x+11` ---> equation of the line into slope intercept form
