Multiple Choice

What key words tell you that you can graph this question in Desmos?

• "Expression is equivalent"

• "All Values of a, b and c"

• "Where the expression is defined"

Multiple Choice

What is the slope of the equation? and How do you find it?

• -19, because it is in slope-intercept form y= mx + b

• 12, because it is in slope-intercept form y= mx + b

• Solve the standard form equation to see the slope

• Graph in Desmos, then see the slope
