In the general form for the equation of a line, y=mx+b, m represents what?
|
m represents the slope of the line.
|
|
|
When graphing a proportional relationship such as distance over time, the slope of the graph can be interpreted as what?
|
The slope of the graph can be interpreted as the unit rate.
|
|
The graph shown here represents how many chips Rebcca eats per hour. The amount of chips Leila eats per hour can be represented by the equation y=15x. Who eats more chips in 3 hours?
|
Leila eats more chips in 3 hours.

|
What is the slope of the line you just graphed?
|
m=5
|
|
Write an equation for the line you just graphed.
|
y=5x
|
|
Write an equation for the line shown on this graph. Show how you calculated the slope.
|
|
|
Find the slope of this line, using similar triangles as a guide.
|
Slope is the ratio between rise and run (or the change in y and the change in x). Both triangles rise 2 places (y) and run 2 places (x), so the slope is 2/2 (or 1)
|
|
