Unit 2 - Milestone Review_P1

If you were to graph the following inequality $$y<2x+1$$ on the coordinate place, would the line be a dashed line or a solid line? Why?

Which of the following graphs represents the solution to the inequality $$y\ge-2x+5$$ ?

Solve this system of equations using the elimination method.

$$x-y=11$$

$$2x+y=19$$

Below is a graph of two lines. What is the solution of these two lines?

Solve the following equation:

$$-10\left(x-1\right)=10-10x$$

Solve this system of equations using the substitution method:

$$y=-3x+5$$

$$5x-4y=-3$$
