STAAR Math Midterm Finals Review

Front

What is the equation to find the total number of toy cars in Ishaan's collection after x months if he starts with 15 cars and adds 4 cars each month?

Back

y = 4x + 15

Front

What does the slope of a line represent in a graph?

Back

The slope represents the rate of change of the line, indicating how much y changes for a unit change in x.

Front

What does the equation 345 + 23x = 677 represent in the context of reading a book?

Back

It represents the situation where Paulina has 677 pages total, has read 345 pages, and reads 23 pages per day.

Front

What does the equation y = -25x - 17 indicate about a scuba diver's depth?

Back

It indicates that the diver starts at 17 meters below sea level and descends at a rate of 25 meters per hour.

Front

What is the starting depth of the scuba diver in the equation y = -25x - 17?

Back

The starting depth is 17 meters below sea level.

Front

How do you interpret the y-intercept in a linear equation?

Back

The y-intercept represents the value of y when x is 0, indicating the starting point of the situation.

Front

What is the significance of the slope in the equation y = mx + b?

Back

The slope (m) indicates the steepness of the line and the direction of the relationship between x and y.

Front

If a diver descends at a rate of 25 meters per hour, how would you express this in an equation?

Back

You would express it as y = -25x + b, where b is the starting depth.

Front

What does it mean if the slope of a line is negative?

Back

A negative slope indicates that as x increases, y decreases, showing an inverse relationship.

Front

In the context of the equation 345 + 23x = 677, what does x represent?

Back

x represents the number of days Paulina will take to finish reading the book.
