Question 689336

Point-slope form of {{{y-7=-3x}}} is 

{{{y=-3x+7}}}


compare to point-slope form {{{y=mx+b}}}, you have a slope {{{m=-3}}} and {{{y-intercept }}}{{{b=7}}} which is a point ({{{0}}},{{{7}}})

we also can find {{{x-intercept }}} if we set {{{y=0}}}:

{{{0=-3x+7}}}

{{{0+3x=-3x+3x+7}}}

{{{3x=7}}}

{{{x=7/3}}}

{{{x=2.33}}}

{{{x-intercept }}}is {{{2.33}}} which is a point ({{{2.33}}},{{{0}}})
