Slope and y-intercept Review Flashcardizz

Front

What does the variable 'm' represent in the slope-intercept form of a linear equation?

Back

The variable 'm' represents the slope of the line.

Front

What is the y-intercept in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, represented as (0, b) where b is the y-intercept value.

Front

Given the equation y = 3/2x + 3, what is the slope and y-intercept?

Back

Slope: 3/2; y-intercept: (0, 3).

Front

How do you write the equation of a line given its slope and y-intercept?

Back

The equation can be written in slope-intercept form as y = mx + b, where m is the slope and b is the y-intercept.

Front

What is the slope of the line represented by the equation y = 1/2x + 3?

Back

The slope of the line is 1/2.

Front

What is the y-intercept of the line represented by the equation y = 3x + 2?

Back

The y-intercept of the line is (0, 2).

Front

How can you determine the slope from two points on a line?

Back

The slope can be determined using the formula m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two points.

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that the line rises from left to right.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that the line falls from left to right.

Front

What is the significance of the y-intercept in real-world applications?

Back

The y-intercept can represent the starting value or initial condition in a real-world scenario.
