Throwback Thursday Flashcardizz Warm-Up

Front

What is the vertex of a parabola given by the equation y = a(x - h)² + k?

Back

The vertex is the point (h, k).

Front

How do you find the vertex of the parabola y = 3(x + 5)² - 4?

Back

The vertex is (-5, -4).

Front

What is the general form of the equation of a line?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

What does the slope of a line represent?

Back

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

Front

What is the slope of the line given by the equation y = 4x + 2?

Back

The slope is 4.

Front

How do you determine the y-intercept from the equation of a line?

Back

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

Front

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

Back

The y-intercept is 5.

Front

What is a zero of a function?

Back

A zero of a function is a value of x that makes the function equal to zero.

Front

How do you find the zero of the function f(x) = 2x - 12?

Back

Set f(x) = 0 and solve for x: 2x - 12 = 0, so x = 6.

Front

What is the equation of a line with a slope of -3 and a y-intercept of 5?

Back

y = -3x + 5.
