HW 11/13: Review for Unit 6, 7 TEST

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 convert an equation from standard form to slope-intercept form?

Back

To convert from standard form (Ax + By = C) to slope-intercept form (y = mx + b), solve for y.

Front

What does the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x, indicating how steep the line is.

Front

What is the formula for the circumference of a circle in terms of diameter?

Back

C = πd, where C is the circumference and d is the diameter.

Front

How do you solve for d in the equation C = πd?

Back

To solve for d, rearrange the equation to get d = C/π.

Front

What is the equation of a line given two points (x1, y1) and (x2, y2)?

Back

The equation can be found using the slope formula m = (y2 - y1)/(x2 - x1) and the point-slope form y - y1 = m(x - x1).

Front

What is standard form of a linear equation?

Back

Standard form is Ax + By = C, where A, B, and C are integers, and A should be non-negative.

Front

How do you convert the equation y = -4x - 3 to standard form?

Back

Rearranging gives 4x + y = -3.

Front

What is the y-intercept of the line y = 3x - 4?

Back

The y-intercept is -4, which is the point where the line crosses the y-axis.

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope and will never intersect.
