Pre-Algebra Review Part 2

Front

What is the slope-intercept form of a linear equation?

Back

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

Front

How do you identify the slope in the equation y = 3x + 2?

Back

The slope (m) is 3.

Front

What does the y-intercept represent in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, represented by the value of b in the equation y = mx + b.

Front

If the slope of a line is negative, what does that indicate about the line's direction?

Back

A negative slope indicates that the line descends from left to right.

Front

What is the y-intercept of the equation y = -2x + 4?

Back

The y-intercept is 4.

Front

How can you find the slope between two points (x1, y1) and (x2, y2)?

Back

The slope (m) can be calculated using the formula m = (y2 - y1) / (x2 - x1).

Front

What does 'm' represent in the equation y = mx + b?

Back

In the equation, 'm' represents the slope of the line.

Front

What is the solution to the equation 2x + 3 = 7?

Back

The solution is x = 2.

Front

How do you convert the equation 4y + 2x = 8 into slope-intercept form?

Back

Rearranging gives y = -1/2x + 2.

Front

What is the slope of the line represented by the equation y = 5?

Back

The slope is 0, indicating a horizontal line.
