TOPIC 1 & TOPIC 2 SPIRAL REVIEW

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.

Front

In the equation y = mx + b, what does 'm' represent?

Back

'm' represents the slope of the line, indicating how steep the line is.

Front

If a scooter rents for $4 plus $1.50 per hour, how would you write this as an equation in slope-intercept form?

Back

The equation is y = 1.50x + 4, where y is the total cost and x is the number of hours.

Front

How do you solve the equation 2 + 5x + 2x = -12?

Back

Combine like terms to get 7x + 2 = -12, then subtract 2 from both sides to get 7x = -14, and finally divide by 7 to find x = -2.

Front

What is the result of the expression -8 + 5?

Back

The result is -3.

Front

When adding numbers with different signs, what should you do?

Back

Subtract the smaller absolute value from the larger absolute value and keep the sign of the larger number.

Front

What is the product of 3/4 and 2/3?

Back

The product is 1/2.

Front

What does the term 'y-intercept' mean 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.

Front

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

Back

The slope is calculated as m = (y2 - y1) / (x2 - x1).
