Math 8 - Slope-Intercept Form

Front

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

Back

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

Front

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

Back

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

Front

What does the y-intercept (b) represent in the slope-intercept form?

Back

The y-intercept b represents the point where the line crosses the y-axis.

Front

Find the equation of the line that passes through the points (1, 2) and (3, 6).

Back

y = 2x.

Front

Given the slope is 4 and the y-intercept is -1, what is the equation of the line?

Back

y = 4x - 1.

Front

What is the slope of the line represented by the equation y = -3x + 5?

Back

The slope is -3.

Front

Find the equation of the line that passes through the points (0, 0) and (2, 8).

Back

y = 4x.

Front

If a line has a slope of 1/2 and passes through the point (2, 3), what is the equation of the line?

Back

y = 1/2x + 2.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.
