Algebra 1 EOC Review 1

Front

Find the slope of the line that passes through (6,7) and (4,2).

Back

The slope (m) is calculated using the formula m = (y2 - y1) / (x2 - x1). For points (6,7) and (4,2), m = (2 - 7) / (4 - 6) = 5/2.

Front

What does the 'm' represent in the slope-intercept form equation (y = mx + b)?

Back

In the equation y = mx + b, 'm' represents the slope of the line.

Front

The slopes of parallel lines are...

Back

The slopes of parallel lines are the same.

Front

What is the slope of a line perpendicular to 5?

Back

The slope of a line perpendicular to a slope of 5 is -1/5.

Front

Solve for a: a = pw, a = p/w, a = w/p, a = w + p.

Back

The correct equation is a = p/w.

Front

What is the formula for calculating the slope of a line?

Back

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

Front

If two lines have slopes of 3 and -1/3, are they parallel, perpendicular, or neither?

Back

The lines are perpendicular because the product of their slopes (3 * -1/3) equals -1.

Front

What is the y-intercept in the equation y = 2x + 3?

Back

The y-intercept is 3, which is the value of y when x = 0.

Front

How do you find the x-intercept of the equation y = 4x - 8?

Back

To find the x-intercept, set y = 0: 0 = 4x - 8, which gives x = 2.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.
