WebThe greater the magnitude of the slope, the steeper the line and the greater the rate of change. By examining the equation of a line, you quickly can discern its slope and y-intercept (where the line crosses the y-axis). The slope is positive 5. When x increases by 1, y increases by 5. The y-intercept is 2. The slope is negative 0.4. WebJul 9, 2024 · The y- intercept is the place where the regression line y = mx + b crosses the y -axis (where x = 0), and is denoted by b. Sometimes the y- intercept can be interpreted in a meaningful way, and sometimes not. This uncertainty differs from slope, which is always interpretable. In fact, between the two concepts of slope and y- intercept, the ...
