Front

What is the slope in the equation y = mx?

Back

The slope 'm' indicates the steepness of the line and the direction it goes. A positive slope means the line rises, while a negative slope means it falls.

Front

How do you find the slope from a table of values?

Back

The slope can be calculated by taking the difference in y-values divided by the difference in x-values between two points: m = (y2 - y1) / (x2 - x1).

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), where (x1, y1) is the point and m is the slope.

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.
