Answer

point slope form $y+3=1(x+2)$ slope intercept form $y=x-2$

Work Step by Step

The slope of line is $m=\frac{y_{2}-y_{1}}{x_(2)-x_(1)}=\frac{2-(-3)}{4-(-1)}=\frac{5}{5}=1$ The point slope form is the following $(y-y_2)=m(x-x_2)$ plugging in the known values we have $y+3=1(x+2)$ The slope intercept form is the following $y=mx+b$ where $b=y_2-mx_2=-3-(1)*(-1)=-2$ plugging in the known values we have $y=x-2$
