Algebra 1: Semester One Final Exam Review Day 2

Front

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

Back

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

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

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

What does the y-intercept represent in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, represented by the value of b in the slope-intercept form y = mx + b.

How do you convert the equation 3y = x + 9 into slope-intercept form?

Back

To convert, divide both sides by 3: y = (1/3)x + 3.

If a banquet costs $80 plus $12 per person, what is the total cost for 58 people?

Back

Total cost = 80 + (12 * 58) = $776.

What is a line of best fit?

Back

A line of best fit is a straight line that best represents the data on a scatter plot, minimizing the distance between the line and all data points.

Front

How do you determine the line of best fit from a graph?

Back

Visually assess the data points and draw a line that has approximately equal numbers of points above and below it.

Front

What is the formula to find the number of chapters in a book if you know the total number of pages and pages per chapter?

Back

Number of chapters = Total pages / Pages per chapter.

Front

If a book has 180 pages and each chapter has 10 pages, how many chapters are there?

Back

Number of chapters = 180 / 10 = 18 chapters.
