Coordinate Grids and Tables

Front

What is a coordinate grid?

Back

A coordinate grid is a two-dimensional plane formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis), used to locate points using ordered pairs (x, y).

Front

What does the equation y = mx + b represent?

Back

This is the slope-intercept form of a linear equation, where 'm' is the slope of the line and 'b' is the y-intercept.

Front

What is the slope in the equation y = 0.2x?

Back

The slope is 0.2, which means for every 1 unit increase in x, y increases by 0.2 units.

Front

How do you find the y-intercept in the equation y = x + 7.55?

Back

The y-intercept is the value of y when x = 0. In this case, it is 7.55.

Front

What are coordinate pairs?

Back

Coordinate pairs are ordered pairs of numbers (x, y) that represent points on a coordinate grid.

Front

What does the term 'linear relationship' mean?

Back

A linear relationship is a relationship between two variables that can be represented by a straight line on a graph.

Front

How can you determine if a point (x, y) lies on the line y = x + 6?

Back

Substitute the x value into the equation and see if the resulting y value matches the given y.

Front

What is the rule for the relationship between List X and List Y if y = 1.5x?

Back

For every value of x in List X, multiply it by 1.5 to find the corresponding value in List Y.

Front

What does it mean if a graph includes only points that follow a specific rule?

Back

It means that all points plotted on the graph satisfy the equation of the rule.

Front

How do you plot a point on a coordinate grid?

Back

Locate the x-coordinate on the x-axis, then move vertically to the y-coordinate and mark the point.
