Question 472467
{{{y = -2x - 7}}}
If the equation of the line is given in the slope intercept  form {{{y=mx+b}}}, then {{{m}}} is the slope
{{{y = -2x - 7}}}  the slope is {{{m=-2}}}
x-intercept:  Let {{{y = 0}}}, substitute in place of {{{y}}} and then solve for {{{x}}}:  {{{0=-2x-7}}}, {{{2x =-7}}}, {{{x=-3.5}}}.
 y-intercept:  Let {{{x = 0}}}, substitute in place of {{{x}}} and then solve for {{{y}}}:  {{{y = -7}}}
