Question

The equations and graph of a system of linear equations are shown.

3x+2y=12
y=-x+5
What is the y-coordinate of the solution to the system of equations?
How many solutions can this system have?

Answer 1

Answer: the two lines intersect the y-axis at 5 & 6, so it can have 2 answers

Explanation:

just count the units up the y-axis (vertical or going up and down) to the places where the two lines cross at it.
