**all**that apply.A.) (-3,6)

B.) (-2,0)

C.) (0,-2)

D.) (6,-3)

E.) (8,2)

**Substitute the (x,y) coordinates into the equation. If it makes a true statement, then the coordinates are a solution. In other words, the point lies on the graph.**

A.) (-3,6)-3x + 6y + 5 = -7 {the equation} -3(-3) + 6(6) + 5 = -7 {substituted} 9 + 36 + 5 = -7 {multiplied} 50 = -7 {added} False, not a point on the line.C.) (0,-2)-3x + 6y + 5 = -7 {the equation} -3(0) + 6(-2) + 5 = -7 {substituted} 0 - 12 + 5 = -7 {multiplied} -7 = -7 {added} True, is a point on the line.E.) (8,2)-3x + 6y + 5 = -7 {the equation} -3(8) + 6(2) + 5 = -7 {substituted} -24 + 12 + 5 = -7 {multiplied} -7 = -7 {added} True, is a point on the line.C.) (0,-2) and E.)
