This lesson will focus on the slope "m" of a linear equation. The picture below shows the parts of linear equations that we need.

2.
If a graph goes down from left to right (--->) it has a negative slope.
Which of the graphs below has a positive slope? (Click all that apply)
The slope is found by finding two points on a line and, moving from left to right
In other words, slope=rise/run

Question 5
5.
Find the slope of the graph below. The graph has been added to the "Show your work" board because it can be helpful for many people if they can draw the slope triangles (start on the point on the left, then draw a line along the gridlines up or down, the right to the next point).

Question 9

For the equation
the first point is at (0,-6) and has been graphed on the "Show your work" board. If you move up or down, then right, what will the next point be?
If you are having trouble getting the right answer, remember that coordinates are written as (x,y) with parentheses, a comma between, and no spaces (when I type in the answers anyway!).

Question 10
10.
For the equation
the first point is at (0,1) and has been graphed on the "Show your work" board. If you move up or down, then right, what will the next point be?
The interactive graph below shows the slope and y-intercept of the line as you move the two points around. You can play around with it to see how the slope changes. Next time, we'll focus on the y-intercept.
