y=mx+b

Front

What does the equation y = mx + b represent?

Back

It represents the equation of a straight line, where m is the slope and b is the y-intercept.

Front

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

Back

The slope (m) indicates the steepness of the line and the direction it goes (upward or downward).

Front

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

Back

The y-intercept (b) is the point where the line crosses the y-axis.

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 = -2x + 5?

Back

The slope is -2.

Front

If a line has a slope of 1/3, what does this mean?

Back

For every 3 units you move to the right, you move up 1 unit.

Front

What is the equation of a line with a slope of 2 and a y-intercept of 3?

Back

y = 2x + 3.

Front

How do you write the equation of a line given a slope and a point?

Back

Use the point-slope form: y - y1 = m(x - x1).

Front

What is the equation of a line that passes through the point (0, 8) with a slope of 5?

Back

y = 5x + 8.

Front

What does it mean if a line has a slope of 0?

Back

The line is horizontal and does not rise or fall.
