Objectives:. Calculate and interpret the slope of a line Graph lines given a point and the slope Use the point-slope form of a line Find the equation of a line given two points Write the equation of a line in slope-intercept form Define parallel, perpendicular, and oblique Lines Find equations
1. Slopes of Equations and Lines Honors Geometry
18. Definition: Oblique Lines Oblique lines are lines that intersect but are not perpendicular to each other.
This means that the slopes of oblique lines are not the same and they are not opposite reciprocals.
The following slopes are slopes of oblique lines.
2/3 and 3/2 -2/3 and -3/2 5/4 and 2/3
1.25 and -1.25 7/4 and 3/7
