The graph of the equation 2x+dy=13 passes through the point (-18, 7). What value of D accurately completes the equation

Respuesta :

since the graph passes point (-18, 7), the value of D accurately completes the equation 2x + dy = 13 can be solve by substituting the given point to the equation

2(-18) + d(7) = 13
-36 + 7d = 13
7d = 13 + 36
7d = 49
d = 7
