Which pair of undefined terms is used to define a ray?
Zigmanuir [339]

Answer:

A point and a line.

Further explanation:

Ray is part of the line with one endpoint. Ray is an endless straight path in one direction from a starting point, e.g., .

The arrow above the point shows the direction of the longitudinal beam. The length of the ray cannot be calculated.

Undefined terms are basic figure that is not defined in terms of other figures. The undefined terms (or primitive terms) in geometry are a point, line, and plane.

These key terms cannot be mathematically defined using other known words.

A point represents a location and has no dimension (size).  It is labeled with a capital letter and a dot.

A line is an infinite number of points extending in opposite directions that have only one dimension. It has one dimension. It is a straight path and no thickness.

A plane is a flat surface that contains many points and lines.  A plane extends infinitely in all four directions.  It is two-dimensional.  Three noncollinear points determine a plane, as there is exactly one plane that can go through these points.

Describe the difference between slope and y-intercept​
Zinaida [17]

Answer:

The difference between slope and y-intercept, is y-intercept is a specific point. Y-intercept is when the line crosses the y-axis, or when x = 0. Slope is how much the y value changes when the x has changed +1, or -1, if that makes sense.

I was gonna do an example, but I got lazy, hehe.

У = 2х – 1<br> у = 3х + 2<br> Using substitution method
sergij07 [2.7K]

Answer:

x = -3, y = -7

Step-by-step explanation:

Eliminate the equal sides of each equation and combine.

Solve 2x - 1 = 3x + 2 for x.

-x - 1 = 2

-x = 3

x = -3

Evaluate y when x = -3

y = 3 (-3) + 2

y = -7

(-3, -7)

<em>good luck, i hope this helps :)</em>
