well, i am doing a math crossword puzzle on linear equations. I really need some help. here are the questions:
what is Ax+By+C called?
what are numbers used to graph a point?
what is not a straight line?
where does a line pass threoug the x-axes?
what is the y values in a set of orderde pairs?
what is a horizontal line?
whats a grid system?
what does y=mx+b mean?
where does a line passs through the y axis
what is a set of ordered pairs
what is up and to the right, into the positives
what is the x values in a set of ordered pairs
if someone can answer them all asap that would be great!!!!
thanks,

Hmmmm! If YOU answered them all, YOU'd learn a lot!
Check your book for these words.
Sure, I would be happy to help you with your math crossword puzzle on linear equations. Let's go through each question one by one:
1. "What is Ax + By + C called?"
The expression Ax + By + C is called the standard form of a linear equation.
2. "What are numbers used to graph a point?"
The numbers used to graph a point on a coordinate plane are called coordinates, specifically an ordered pair (x, y), where x represents the horizontal value (abscissa) and y represents the vertical value (ordinate) of the point.
3. "What is not a straight line?"
A curve or a nonlinear line is not a straight line.
4. "Where does a line pass through the x-axis?"
A line passes through the x-axis at the point where the y-coordinate is equal to zero. This point is called the x-intercept.
5. "What are the y-values in a set of ordered pairs?"
The y-values in a set of ordered pairs represent the vertical values or the ordinates of the points.
6. "What is a horizontal line?"
A horizontal line is a straight line that runs parallel to the x-axis. It has a constant y-value, meaning all points on the line have the same y-coordinate.
7. "What's a grid system?"
A grid system is a system of parallel horizontal and vertical lines that intersect at right angles. It is used to locate and identify points on a coordinate plane.
8. "What does y = mx + b mean?"
The equation y = mx + b is the slope-intercept form of a linear equation. In this equation, m represents the slope (the rate of change) and b represents the y-intercept (the point where the line crosses the y-axis).
9. "Where does a line pass through the y-axis?"
A line passes through the y-axis at the point where the x-coordinate is equal to zero. This point is called the y-intercept.
10. "What is a set of ordered pairs?"
A set of ordered pairs is a collection of pairs (x, y) where x and y are related in some way. In the context of graphing, each ordered pair represents a point on a graph.
11. "What is up and to the right, into the positives?"
Moving up and to the right, into the positive direction, refers to increasing values of both x and y coordinates on a coordinate plane.
12. "What are the x-values in a set of ordered pairs?"
The x-values in a set of ordered pairs represent the horizontal values or the abscissas of the points.
I hope these explanations help you solve your math crossword puzzle! Let me know if you have any further questions.
