Answer:

From general linear equation;


{ \rm{y = mx + c}}

m is the slope;


{ \rm{y = - (1)/(2)x + c }}

• When x is -2 and y is 3;


{ \tt{3 = - ((1)/(2) * - 2) + c}} \\ \\ { \tt{3 = 1 + c}} \\ { \tt{c = 2}}

Therefore our line has equation of


{ \boxed{ \tt{y = - (1)/(2)x + 2 }}}

OTHER POINTS.


{ \tt{ \red{ {1}^(st) \dashrightarrow \: (0, \: 2)}}}


  • { \rm{when \: x = 0, \: \: y = ( - (1)/(2) * 0) + 2 }} \\ { \rm{y = 2}}


{ \blue{ \tt{ {2}^(nd) \dashrightarrow \: (4, \:0) }}}


  • { \rm{when \: x = 4, \: \: y = ( - (1)/(2) * 4) + 2 }} \\ { \rm{y = - 2 + 2 = 0}}


{ \green{ \tt{ {3}^(rd) \dashrightarrow \: (6, \: - 1)}}}

substitute for x as 6
