FLASHCARD QUESTION
Front
What does the slope of a line represent?
Back
The slope of a line represents the rate of change of y with respect to x. It indicates how steep the line is and the direction it goes (upward or downward).

FLASHCARD QUESTION
Front
What is the y-intercept in a linear equation?
Back
The y-intercept is the point where the line crosses the y-axis. It is represented by the value of b in the equation y = mx + b.

FLASHCARD QUESTION
Front
How do you determine if an equation matches a table of values?
Back
To determine if an equation matches a table of values, substitute the x-values from the table into the equation and see if the resulting y-values match those in the table.

What is the function of the equation y = x - 3?
Back
The function of the equation y = x - 3 is to show that for every unit increase in x, y increases by the same amount, but starts 3 units lower.

FLASHCARD QUESTION
Front
What is the significance of the coefficient in front of x in a linear equation?
Back
The coefficient in front of x (the slope) indicates how much y changes for a unit change in x. A larger coefficient means a steeper slope.
