Solve: \(\quad 8(x-2)-2(x-3) \leq 8 x\).

Will help you prepare for the material covered in the next section. In each exercise, evaluate $$\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$$ for the given ordered pairs \(\left(x_{1}, y_{1}\right)\) and \(\left(x_{2}, y_{2}\right)\). \(\left(x_{1}, y_{1}\right)=(1,3) ;\left(x_{2}, y_{2}\right)=(6,13)\)

What is the graph of an equation?

Explain how to graph an cquation in two variables in the rectangular coordinate system.

determine whether each statement 鈥渕akes sense鈥� or 鈥渄oes not make sense鈥� and explain your reasoning. When I know that an equation's graph is a straight line, I don't need to plot more than two points, although I sometimes plot three just to check that the points line up.

determine whether each statement 鈥渕akes sense鈥� or 鈥渄oes not make sense鈥� and explain your reasoning. The graph that I'm looking at is U-shaped, so its equation cannot be of the form \(y=m x+b\)

determine whether each statement 鈥渕akes sense鈥� or 鈥渄oes not make sense鈥� and explain your reasoning. I'm working with a linear equation in two variables and found that \((-2,2),(0,0),\) and \((2,2)\) are solutions.

I'm working with a linear equation in two variables and found that \((-2,2),(0,0),\) and \((2,2)\) are solutions. When a real-world situation is modeled with a linear cquation in two variables, I can use its graph to predict specific information about the situation.
