What are the units of a slope?
the slope is a ratio and really has no units.
Can the slope of a line be a fraction?
Of course. If the line rises 18 units for every 27 horizontal units,then its slope is 2/3 .
What does the mx in y equals mx plus b?
y=mx+b Y is the value on the vertical axis, the dependent variable. X is the value on the horizontal axis, the independent variable. m is the slope of the line. Slope is rise/run. The equation for slope is m=(y2-y1)/(x2-x1). It describes how many units up or down the graph travels for every unit traveled to the right. (If it's written as a fraction, like 2/5, that means two units up for every five units right). b is the y-intercept. This is the y value when the x value is 0, when the line crosses the y-axis.
What is the slope of -4x2?
The slope changes as the value of x changes. For any point x, the slope is -8x.
What can you determine about the steepness of a line in terms of its slope?
Its steepness is the absolute value of its slope.
