Which system of equations shows a solution of (0.5, –1)?

The graph in the attached figure

Step-by-step explanation:

we know that

The solution of a system of linear equations is the intersection point both lines

If the solution is the point (0.5,-1)

then

that means that the intersection point both lines is x=0.5 and y=-1

so

The intersection point belong to the IV Quadrant

therefore

The graph in the attached figure

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180

step-by-step explanation:

there were a lot of them but the first one to pop up on a google search was bts
