Finding x and y intercepts (and flashcard review)

Front

What is the y-intercept of the equation y = 3x + 8?

Back

(0, 8)

Front

Convert the equation y = -3x + 5 into standard form.

Back

3x + y = 5

Front

Back

-6

Front

What point would you use to graph the equation y - 7 = 3(x + 9)?

Back

(-9, 7)

Front

True or False: The y-intercept of a function ALWAYS occurs where y is equal to zero.

Back

False

Front

What is the definition of the y-intercept?

Back

The y-intercept is the point where a line crosses the y-axis, represented as (0, y).

Front

How do you find the y-intercept from an equation in slope-intercept form?

Back

Set x = 0 and solve for y.

Front

What is the standard form of a linear equation?

Back

Ax + By = C, where A, B, and C are integers.

Front

What does the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x.

Front

How do you convert from slope-intercept form to standard form?

Back

Rearrange the equation to the form Ax + By = C.
