Question

If a line contains the point (0, -1) and has a slope of 2, then which of the following points also lies on the line?
a)(2, 1)
b)(1, 1)
c)(0, 1)

Answer 1

Answer:

B is the point.

find the equation to line , then put the co-ordinates.

Step-by-step explanation:

y - y1 = m(x - x1) ; put(0,1) as (x1,y1);

= y + 1 = 2x - 0

= 2x - y = 1;

now put options in x1 and y1 the one which satisfies equation is ans.

Try b (1 ,1):

(2 × 1) - 1= 1;

2-1 =1;

1=1;

equation satisfied.
