Question

A line passes through the point (0, –1) and has a slope of -2/3 What is the equation of the line?

A. y=-2/3x-1
B. y=3/2x+1
C.y=2/3x+1
D. -2/3x+1

Answer 1

The slope formula:

`y=mx+b`
m - a slopeb - y-intercept
We have:

`m=-(2)/(3)` and point
`(0;-1)\to b=-1`
Substitute:

`y=-(2)/(3)x-1`
Answer: A.
