Question

Help with a graph problem pleaseeeeee graph the line with slope -1/2 passing through the point (-1,2)

Answer 1

When you know the slope $m$ and a point $(x_0,y_0)$ of a line, the equation of the line is given by

$y-y_0=m(x-x_0)$

So, your line is given by

$y-2=-\dfrac{1}{2}(x+1) \iff y=-\dfrac{1}{2}x-\dfrac{1}{2}+2=-\dfrac{1}{2}x+\dfrac{3}{2}$
