Identify the slope and y-intercept

Front

What is the slope in the equation y = mx + b?

Back

The slope (m) represents the rate of change of y with respect to x.

Front

What is the y-intercept in the equation y = mx + b?

Back

The y-intercept (b) is the value of y when x = 0.

Front

Calculate the slope of the line represented by the equation y = 3x + 5.

Back

The slope is 3.

Front

Calculate the y-intercept of the line represented by the equation y = -x + 4.

Back

The y-intercept is 4.

Front

If the slope of a line is 2, what does this mean?

Back

For every 1 unit increase in x, y increases by 2 units.

Front

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates a horizontal line.

Front

What does an undefined slope indicate about a line?

Back

An undefined slope indicates a vertical line.

Front

Identify the slope and y-intercept of the equation y = -4x + 1.

Back

Slope: -4, Y-intercept: 1.

Front

If a line passes through the points (1, 2) and (3, 6), what is the slope?

Back

The slope is 2.

Front

What is the formula to calculate the slope between two points (x1, y1) and (x2, y2)?

Back

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