Back
A linear equation is an equation that makes a straight line when graphed. It can be written in the form y = mx + b, where m is the slope and b is the y-intercept.
2.
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 (positive or negative).
3.
FLASHCARD QUESTION
Front
How do you find the slope from two points (x1, y1) and (x2, y2)?
Back
The slope (m) can be calculated using the formula m = (y2 - y1) / (x2 - x1).

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 can you determine if a linear equation is in slope-intercept form?
Back
A linear equation is in slope-intercept form if it is written as y = mx + b, where m is the slope and b is the y-intercept.

FLASHCARD QUESTION
Front
What does the equation y = 2/3x - 3 represent?
Back
This equation represents a line with a slope of 2/3 and a y-intercept of -3.

FLASHCARD QUESTION
Front
How do you graph a linear equation?
Back
To graph a linear equation, identify the y-intercept, plot it on the graph, then use the slope to find another point and draw a straight line through the points.
