Question

Straight line passing through the points (-1, 1), (0, 0) and (1, -1) has equation​

Answer 1

this is the correct equation bro 3x+45y=73

Answer 2

SOLUTION

TO DETERMINE

The equation of the Straight line passing through the points (-1, 1), (0, 0) and (1, -1)

EVALUATION

Let the equation of the straight line be

$\sf{}y = mx + c \: \: ....(1)$

Where m = slope of the line and c = y - intercept

Now the equation (1) passes through the point (0,0)

So

$\sf{}0 = 0 + c$

$\implies \sf{}c = 0$

So equation (1) reduces to

$\sf{}y = mx \: \: ....(2)$

Again equation (2) passes through the point (-1,1)

So

$\sf{}1 = - m \: \:$

$\implies \sf{}m = - 1$

So equation (2) reduces to

$\sf{}y = - x$

Which is the required equation of the line

FINAL ANSWER

The equation of the Straight line passing through the points (-1, 1), (0, 0) and (1, -1)

$\sf{}y = - x$
