Question

Straight line passing through the points ( -1,3) (0,2) and (2,0 ) has equation A) y = x + 2. B) y = x -2. C) y = 2 -x. D) none of these.

Answer 1

Answer:

C

Step-by-step explanation:

Equation of line of form y=mx+c

m is slope=y2-y1/x2-x1

2-3/1=-1 (taking point 1 and 2)

Slope of line= -1

and c=When x=0

y=c

x=0 and y is 2 (point 2)

hnce line is

y= -x+2 or y=2-x

Answer 2

Y = -x + 2
