Algebra 1 Semester 1 Review

Front

What does the equation x=2 represent on a graph?

Back

A vertical line that crosses the x-axis at 2.

Front

How do you find the slope of a line given two points?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

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

Back

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

Front

How can you determine the y-intercept from the equation y = mx + b?

Back

The y-intercept is the value of b in the equation.

Front

What does a negative slope indicate about a line?

Back

The line decreases as it moves from left to right.

Front

What is the slope of the line represented by the equation y = 4x + 3?

Back

The slope is 4.

Front

How do you write the equation of a line in slope-intercept form?

Back

Identify the slope and y-intercept from the graph or points.

Front

What does the graph of y = -x + 2 look like?

Back

A line that decreases with a y-intercept at 2.

Front

What is the significance of the point where a line crosses the y-axis?

Back

It is the y-intercept of the line.

Front

How can you identify the slope from a graph?

Back

By calculating the rise over run between two points on the line.
