Algebra 1 Semester 1 Practice Exam - Attempt 1

Front

What is the equation of a horizontal line that passes through the point (−2, −3)?

Back

The equation is y = -3.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

What is the equation of a vertical line that passes through the point (−2, −3)?

Back

The equation is x = -2.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

How do you solve the equation 4(2x + 1) = 27 + 3(2x − 5)?

Back

First, distribute: 8x + 4 = 27 + 6x - 15. Then combine like terms and isolate x to find x = 4.

Front

What is the y-intercept of a linear function?

Back

The y-intercept is the point where the graph crosses the y-axis.

Front

If a linear function has a slope of -0.2, what does this indicate about the function?

Back

It indicates that for every 1 unit increase in x, y decreases by 0.2 units.

Front

What is the general form of a linear equation?

Back

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

Front

What does the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x.

Front

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

Back

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