Front

How do you find the x-intercept of a linear equation?

Back

Set y = 0 and solve for x.

Front

How do you find the y-intercept of a linear equation?

Back

Set x = 0 and solve for y.

Front

What is the slope of the line represented by the equation y = 7/5x + b?

Back

Slope = 7/5

Front

What does the slope of a line represent?

Back

The rate of change of y with respect to x.

Front

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

Back

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

Front

If a line has an x-intercept of 3, what does this mean?

Back

The line crosses the x-axis at the point (3, 0).

Front

If a line has a y-intercept of -5, what does this mean?

Back

The line crosses the y-axis at the point (0, -5).

Front

What is the significance of the y-intercept in a linear equation?

Back

It represents the value of y when x = 0.
