Question

1) What is the slope of x+y=4?

2) What is the slope of 2x+2y=8?

3) Do these two lines have the same y-intercept?

4) How can you relate the slopes and y-intercepts of each equation to the number of solutions for the linear system of equations?

(The number of solutions for the system is infinite)

Thank you!!! :D

Answer 1

1) y=-x+4, the slope is -1
2)y=-x+4, slope is -1
3) yes
4)It's the same line if the slopes and y-intercepts are the same, so the number of corresponding points are infinite.
