What is the range of a graph?

Back

The range of a graph is the set of all possible output values (y-values) that a function can produce. For example, if the range is 1 ≤ y ≤ 5, it means y can take any value from 1 to 5, inclusive.

Solve for a: 2a + 10 = 0

Back

a = -5

Find the slope of the line passing through the points (1, 2) and (4, -1).

Back

Slope (m) = (y2 - y1) / (x2 - x1) = (-1 - 2) / (4 - 1) = -3/3 = -1.

Front

Solve for a: 3a - 6 = 0

Back

a = 2

What is the value of x when f(x) = 16 for the function f(x) = x^2?

Back

x = 4 and x = -4.

Front

What is a linear equation?

Back

A linear equation is an equation that makes a straight line when graphed. It can be written in the form 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 of a line represents the rate of change of y with respect to x. It indicates how steep the line is and the direction it goes (positive or negative).

Front

What is the y-intercept of a line?

Back

The y-intercept is the point where the line crosses the y-axis. It is the value of y when x = 0.

Front

How do you find the x-intercept of a linear equation?

Back

To find the x-intercept, set y = 0 in the equation and solve for x.

Front

What is the difference between independent and dependent variables?

Back

The independent variable is the variable that is changed or controlled in an experiment, while the dependent variable is the variable that is measured or affected.
