(-6,-2);(0,9);(3,0);(6,2);(8,2)
What is YES
What is do the m and b represent in slope intercept form?
What are m is slope, b is y-intercept
What is slope-slope intercept form? What is Standard form? What is Point-slope form? (Must list all 3)
y=mx+b

When solving a system by graphing what are you looking for on the graph?
What is the intersection point.
When graphing inequalities what is the difference between a solid line and dashed line
Solid line means values on line are included in the solution, while dashed means they are not .
I am all of the x values included in a function.
What is the domain.
What is standard form of a linear function? And what CAN'T the A value be?
What is Ax + By = C; A>= 1
Formula for slope
y2-y1 divided by x2-x1
When solving a system of equation algebraically, after you find one variable, how do you find the remaining variable?
What is substitution.
When solving a system of inequalities, graphically, where does the solution lie?
In the shaded region
I am all of the y values included in a function.
What is the range.
What is point-slope form and how do you find slope given 2 points?
