The standard form of a linear equation is Ax + By = C. When we want to find the slope of the line represented by this equation, we have two options. We can put the equation in slope-intercept form and identify the slope that way, or we can use the formula m = -A/B.

The slope-intercept form of a line is: y=mx+b where m is the slope and b is the y-intercept. The y-intercept is always where the line intersects the y-axis, and will always appear as (0,b) in coordinate form.

A higher positive slope means a steeper upward tilt to the curve, which you can see at higher output levels. A negative slope that is larger in absolute value (that is, more negative) means a steeper downward tilt to the line. A slope of zero is a horizontal line. A vertical line has an infinite slope.

When you look at the two lines, you can see that the blue line is steeper than the red line. It makes sense the value of the slope of the blue line, 4, is greater than the value of the slope of the red line, . The greater the slope, the steeper the line. The next example shows a line with a negative slope.

letter m

In math, steeper means bigger so the slope of that line is bigger than the slope of the second skater’s line. You may also notice that the skaters are going down the ramp from the left to the right. This makes the slope decreasing, or negative.

To find the slope of a feature, the horizontal distance (run) as well as the vertical distance (rise) between two points on a line parallel to the feature need to be determined. The slope is obtained by dividing the rise over run. Multiply this ratio by 100 to express slope as a percentage.

Explore the slope, elevation, and distance along a path.

- Open Google Earth Pro.
- Draw a path or open an existing path.
- Click Edit. Show Elevation Profile.
- An elevation profile will appear in the the lower half of the 3D Viewer. If your elevation measurement reads “0,” make sure the terrain layer is turned on.
