Answer:

(-1,4) is a solution to the system.

Step-by-step explanation:

For this problem, we can simply identify if this point is a solution by verifying the plugged in point values allow the left hand side to equal the right hand side.

(1) -2x - 3y = -10

 -2(-1) - 3(4) ?= -10

 2 - 12 ?= -10

 -10 == -10

(2) -3x + y = 7

 -3(-1) + (4) ?= 7

 3 + 4 ?= 7

 7 == 7

Since both equations are satisfied by this point, then we can say the point (-1,4) is a solution to the system.  Additionally, this means this is a crossing point of the system of equations.

Cheers.

Need help what are the classifications of each system
ratelena [41]
You can graph them on Desmos, then use this attachment to find out the classification.

In the first system, they're the same line and have infinitely many solutions, therefore the answer is consistent, dependent.

In the second system, they're parallel lines with no solution, therefore the answer is inconsistent.

In the third system, they intersect and they have one solution, therefore the answer is consistent, independent.

In the fourth system, they're the same line and have infinitely many solutions, therefore the answer is consistent, dependent.
