what is the slope of the equation y = 11 + 1.25x

3 answers

The equation y = 11 + 1.25x is in slope-intercept form, y = mx + b, where m represents the slope.

In this case, the coefficient of x is 1.25, so the slope of the equation is 1.25.
What does the slope mean in context?
In the equation y = 11 + 1.25x, the slope of 1.25 represents the rate of change or the amount by which y increases for every unit increase in x.

For example, if x increases by 1 unit, y will increase by 1.25 units. If x increases by 2 units, y will increase by 2.5 units (1.25 * 2).

So, the slope of 1.25 indicates that for every unit increase in x, y increases by 1.25.
