Question

A line passes through the points (–5, 2) and (10, –1). Which is the equation of the line?

y = negative one-fifth x + 1
y = one-fifth x + 3
y = –5x – 23
y = 5x + 27

Answer 1

y= -1/5x+1

Explanation:

The slope of (-5,2)and (10,-1) is -1/5.

2-(-1)/(-5-10)= -1/5

So, the points pass through y= -1/5x+1.

Answer 2

A

Explanation:

slope=(-1-2)/(10+5)=-3/15=-1/5

eq. of line is y-2=-1/5(x+5)

or y=-1/5x -1+2

or y=-1/5 x+1
