Testing Solutions to Systems

Is the points (-4, 4) a solution to the system of equations?

• Yes

• No

How can you tell if a point is a solution to a system?

• It makes the first equation true.

• The (x,y) coordinates satisfy both equations

• It makes logical sense

• It makes neither equation negative

Determine if (4, 1) is a solution for the system of equations.
y = -x + 5
y = 2x - 7

Test if point (-1, 4) is a solution to the system:

x= 7 - 2y

2x + y = 5

​ ​ (a)   = 7 - 2 * ​( (b)   )

2* (​ (c)   ) + ​ (d)   = 5

• -1

• 4

• -4

• 1
