Question

the coordinate at which a line crosses the x - axis is known as the x - blank.
to verify if two lines are parallel, their slopes must be blank.
when plotting a line on a graph, the blank dictates how steep or flat the line will appear.
the blank form of a lines equation is helpful for quickly identifying the slope and y - intercept.
two lines that meet to form right angles are said to be blank.
a horizontal line has a slope of blank, indicating no vertical change as it moves across the coordinate plane.
the blank of a geometric figure like a triangle or rectangle on a coordinate plane often involves calculating the slopes of its sides.

Explanation:

1. The coordinate where a line crosses the x - axis is called the x - intercept.
2. Parallel lines have equal slopes.
3. The slope of a line determines its steepness or flatness on a graph.
4. The slope - intercept form ($y = mx + b$) helps in identifying slope ($m$) and y - intercept ($b$).
5. Lines that meet at right angles are perpendicular.
6. A horizontal line has a slope of 0 as there is no vertical change.
7. Analyzing the properties of a geometric figure on a coordinate plane often involves slope calculations of its sides.

Answer:

1. intercept
2. equal
3. slope
4. slope - intercept
5. perpendicular
6. 0
7. analysis
