Front

What is the y-intercept?

Back

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

Front

Solve for x: 3(5x + 10) + 10 = 6x - (x + 10)

Back

x = -5

Front

Find the slope of the line given two points (2, 3) and (4, 4)

Back

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

Front

What is the first step to solve the formula for r in the equation A = rt?

Back

Divide each side by t.

Front

How many solutions does the equation 3x - 20 = 3x + 2 have?

Back

No Solution

Front

What is the definition of a linear equation?

Back

A linear equation is an equation that makes a straight line when graphed. It has the form y = mx + b.

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 slope of a line given two points (x1, y1) and (x2, y2)?

Back

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