Writing Linear Equations TEST 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

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

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

Front

What does it mean for two lines to be perpendicular?

Back

Two lines are perpendicular if the product of their slopes is -1.

Front

Write the equation of a line with a slope of 3 that passes through the point (1, 2).

Back

The equation is y = 3x - 1.

Front

What is the y-intercept of the line represented by the equation y = -2x + 5?

Back

The y-intercept is 5.

Front

Convert the standard form equation 2x + 3y = 6 into slope-intercept form.

Back

The slope-intercept form is y = -rac{2}{3}x + 2.

Front

What is the slope of the line represented by the equation y = rac{1}{4}x + 2?

Back

The slope is rac{1}{4}.

Front

If a line crosses the x-axis at (4, 0), what is the x-intercept?

Back

The x-intercept is 4.

Front

Write the equation of a line that is parallel to y = 2x + 3 and passes through the point (0, -1).

Back

The equation is y = 2x - 1.

Front

What is the formula to convert Celsius to Fahrenheit?

Back

The formula is F = rac{9}{5}C + 32.
