Benchmark Practice Test 1

Front

What are the x- and y-intercepts on a graph?

Back

The x-intercept is the point where the graph crosses the x-axis (y=0), and the y-intercept is the point where the graph crosses the y-axis (x=0). For example, in the points (5,0) and (0,5), (5,0) is the x-intercept and (0,5) is the y-intercept.

Front

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

Back

'm' represents the slope of the line, which indicates the steepness and direction of the line.

Front

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

Back

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

Front

What is the slope of the line through the points (20, -7) and (-13, -19)?

Back

The slope is 12/33.

Front

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

Back

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

Front

If m=3 and b=6, what is the slope-intercept equation?

Back

The equation is y = 3x + 6.

Front

What is the y-intercept of the line represented by the equation y = -4x + 8?

Back

The y-intercept is (0, 8).

Front

What does the term 'intercept' mean in graphing?

Back

An intercept is a point where a line crosses an axis on a graph.

Front

How can you find the x-intercept of a linear equation?

Back

To find the x-intercept, set y = 0 in the equation and solve for x.

Front

How can you find the y-intercept of a linear equation?

Back

To find the y-intercept, set x = 0 in the equation and solve for y.
