FLASHCARD QUESTION

Front

What is the slope-intercept form of a linear equation?

Back

The slope-intercept form of a linear equation is given by y = mx + b, where m is the slope and b is the y-intercept.

2.

FLASHCARD QUESTION

Front

How do you calculate the slope (m) between two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated using the formula m = (y2 - y1) / (x2 - x1).

3.

FLASHCARD QUESTION

Front

What is the y-intercept in the equation y = mx + b?

Back

The y-intercept (b) is the value of y when x = 0, representing the point where the line crosses the y-axis.

4.

FLASHCARD QUESTION

Front

Given points (0, 1) and (4, 4), what is the slope of the line?

Back

The slope is m = (4 - 1) / (4 - 0) = 3/4.

5.

FLASHCARD QUESTION

Front

Write the slope-intercept form of the line through (0, 1) and (4, 4).

Back

y = 3/4x + 1.

6.

FLASHCARD QUESTION

Front

Given points (4, -5) and (-4, -1), what is the slope of the line?

Back

The slope is m = (-1 - (-5)) / (-4 - 4) = 4 / -8 = -1/2.

7.

FLASHCARD QUESTION

Front

Write the slope-intercept form of the line through (4, -5) and (-4, -1).

Back

y = -1/2x - 3.
