Question

Write the equation of the line that passes through (–1, 4) with a slope of –1 in standard form.

Answer 1

equation of the line y=mx+c
where m is slope
find c value by substituting (–1, 4) in x,y place

Answer 2

ok thnx

Answer 3

An alternate method is to use the point-slope form, then convert it to standard form.\[y-4=-(x+1) \implies y=-x+3 \implies x+y=3\]The third equation is in general form, called standard form in some texts.

Answer 4
