Question

A line goes through the point (5,-7) and has slope m=2. Write the equation that represents the line.

This question is rather urgent so please do respond! :)

Answer 1

$\huge\sf{answer:-}$

➽Formula of a line in Slope-point form

If m is the slope and (x1,y1) is a point on the line then equation is given by

•(y - y1 ) = m(x - x1)(y−y1)=m(x−x1)

•From given info x1 is 5 and y1 is -7

slope m is -3

•Putting these in above equation

y+7= -3×(x-5)

•Simplifying will give.

3x + y=8
