Finding x and y intercepts (and flashcard review)

Front

What is the x-intercept of the equation 3x + 8y = 24?

Back

(8, 0)

Front

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

Back

Slope (m) = (y2 - y1) / (x2 - x1)

Front

What is the y-intercept of the equation 3x + y = 5?

Back

(0, 5)

Front

What are the x- and y-intercepts of the equation 5x + 0y = 25?

Back

(5, 0), (0, 5)

Front

Write the equation in point-slope form given the point (2, 5) and slope 4.

Back

y - 5 = 4(x - 2)

Front

What is the definition of an x-intercept?

Back

The x-intercept is the point where a line crosses the x-axis (y=0).

Front

What is the definition of a y-intercept?

Back

The y-intercept is the point where a line crosses the y-axis (x=0).

Front

How do you determine the x-intercept from the equation 3x + 8y = 24?

Back

Set y = 0 and solve for x.

Front

How do you determine the y-intercept from the equation 3x + y = 5?
