• 
• 
• 

Answer explanation

The slope of a line is also known as the Rise Over the Run

• True
• False

Answer explanation

Yes, to find the slope of a line given two points on the line, one can move from left to right by either rising (+) or going down (-) and then running across.

What is the slope of a line whose equation is y = -4x + 1?

Answer explanation

The slope of a line written in the form y = mx + b is the coefficient of the x value.
