Question 1059529
If a line passes through (3,-1) and has a slope of -1,how would you write the equation?
<pre>Use the point-slope formula: {{{y - y[1] = m(x - x[1])}}}
y - - 1 = - 1(x - 3) ------ Substituting (3, - 1) for {{{matrix(1,5, "(", x[1], ",", y[1], ")")}}}, and - 1 for m
y + 1 = - x + 3 =====> y = - x + 3 - 1 =====> {{{highlight_green(y = - x + 2)}}}
