Example Problem. What is the predicted navigation time if a user takes 10 clicks?y-intercept. We know that (meanx, meany) is on the regression line.
We use these values plus the slope in the equation of a line Finally, write the equation, substituting numerical values in for m and b. Check your equation by picking a point on the line (not the y-intercept) and plugging it in to see if it satisfies the equation. Example 1: Write an equation of the following line in slope-intercept form Step 2: The slope intercept form of a line equation is given by. y mx b. WhereTherefore, Slope 0.4. y intercept - 0.8. Example problem 3 The equation of a line is: y mx b so for all of your equations above whatever number is in front of the x is your slope. but if you move the x to the other side dont forget to change the sign. Example 6)They are parallel because the slopes are equal positive 1 for both. Every straight line can be represented by an equation: y mx b. The coordinates of every point on the line will solve the equation if you substitute them in the equation for x and y.Examples. Workout.

In other words, given a "word problem" modelling something in the real world, or an actual real-world linear model, what do the slope and intercept of the modelling equationIn the example from above, the y-intercept would be the population when the sociologists started keeping track of the population. If we know the slope and the y-intercept we can easily nd the equation that rep-resents the line. Example 2.Lines with zero slope or no slope can make a problem seem very dierent. Zero slope, or horiztonal line, will simply have a slope of zero which when multiplied by x gives zero. Published on Jul 14, 2015.
