Question

find the equation of the line through (-2,3) with slope -4
​

Answer 1

Answer:

Let the equation of line is

y=mx+c

Where m is the slope and c is a constant.

So here m= - 4

So the equation becomes

y= - 4x+c

The line pass through (-2,3) thus this point is a solution of the equation.

So 3=-4*(-2)+c

Or, c=3-8=-5

The equation of the line is

y= - 4x - 5

Or, y+4x+5=0
