Have them right the slope formula down on a note card and make them use that formula until they can remember it.
Answer:the diagonal line on a graph
Step-by-step explanation
The first thing to do in this case is to graph both equations
y = 2x +1
y = / x /
Once graphed, you must evaluate points in the Cartesian plane that satisfy the inequations to know where the solution set is.
For this case, the solution set is in the shaded region, or equivalently, quadrants 1 and 2.
answer quadrants 1 and 2.
B:(3,-4)
2x-(-x-1)=10
X=3
Y=-3-1
Y=-4
