Slope-Intercept Form and Y-Intercept

Front

What is the y-intercept of the line represented by the equation y = mx + b?

Back

The y-intercept is the value of y when x = 0, represented by 'b' in the equation.

Front

Determine the slope and y-intercept from the equation: y = 3/2x + 3.

Back

Slope: 3/2, Y-intercept: (0, 3)

Front

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

Back

'b' represents the y-intercept of the line.

Front

Solve for y: 3x + y = 12.

Back

y = -3x + 12

Front

What is the y-intercept for the graph of the equation y = -2x + 5?

Back

The y-intercept is 5.

Front

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

Back

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

Front

What is the slope of the line represented by the equation y = 4x - 1?

Back

The slope is 4.

Front

If the slope of a line is 0, what does that indicate about the line?

Back

The line is horizontal.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

Convert the equation 2y - 4x = 8 to slope-intercept form (y = mx + b).

Back

y = 2x + 4.
