Question 935125


{{{y = 3x + 2}}}:this is equation of a line (linear function, a graph is a line)

 here you have one point (or ordered pair, {{{x}}} and {{{y}}} coordinates) that lie on a given line:

({{{x}}},y )=({{{1}}},{{{y}}} ); so, you are given {{{x}}} coordinate and you need to find {{{y}}} coordinate, and you can find it using given equation

{{{y = 3x + 2}}}...plug in {{{1}}} for {{{x}}}

{{{y = 3*1 + 2}}}...solve for {{{y}}}

{{{y = 3+ 2}}}

{{{y = 5}}}

so, your point is ({{{1}}},{{{5}}} ) and your answer is

 c. {{{5}}}


here is a graph:

{{{drawing( 600, 600, -10, 10, -10, 10,circle(1,5,.13),locate(1,5,p(1,5)), graph( 600, 600, -10, 10, -10, 10, 3x+2)) }}}
