Slope of vertical and horizontal lines
  • The slope of a vertical line is undefined. This is because any vertical line has a x or "run" of zero. Whenever zero is the denominator of the fraction in this case of the fraction representing the slope of a line, the fraction is undefined. The picture below shows a vertical line (x=1)
  • The slope of a horizontal line is zeroThis is because any horizontal line has a . Y or "rise" of zero. Therefore, regardless of what the run is (provided its' not also zero!), the fraction representing slope has a zero in its numerator. Therefore, the slope must evaluate to zero. Below is a picture of a horizontal line...you can see that it does not have any 'rise' to it.
Formula to find the slope of a line
  • Example 1of the Slope of A line
  • The slope of a line through the points (1, 2) and (2, 5) is 3 because every time that the line moves up three (the change in y or the rise) the line moves to the right (the run) by 1.
  • Illustrated Example Two
  • The slope of a line going through the point (1,2) and the point (4,3) is 1/3.

What is a slope used for?

It shows the relationship of y in terms of x. [y = (yIntercept) + ((slope)*(x))] [slope = (y2 - y1)/(x2 - x1)]


What is the slope and yintercept of y plus 4x plus 3?

There is no slope nor intercept because there is no equation, simply an expression.


How do you write an equation of a line that passes through the xintercep and yintercept?

You can write it either in standard form (ax + by = c) or in slope-intercept form (y = mx + b)


What are the slope and yintercept of line 5x 10y 15?

Without the inclusion of an equality sign and not knowing the plus or minus values of the given terms it can't be considered to be a straight line equation


How do you find the slope and y-intercept of an equation?

first of all, i dont see how slope and yintercept has anything to do with shopping. usually in an equation, y= mx+b, m stands for slope, and b is the y-intercept. x and y are just x and y. If the equation is mixed up, and is not in y=mx+b format, you need to solve to get y on one side, the slope, x, and whatever the presented constant is (which is the y-intercept) on the other side. hope this helps.

What would the equation of a line be if it went through the point 2 comma 2 and its yintercept was 10?

We know that the line passes through points (2, 2) and (0, 10) (since the y-intercept is 10).Using these two points, we can find the slope of the line,m = (10 - 2)/(0 - 2) = 8/-2 = 4/-1 = -4.Now by using the slope, m = -4, and the y-intercept, 10, we can write the equation of the line in the slope-intercept form, y = mx + b which isy = -4x + 10.

What does the slope examples of rates inclued?

Why do we need to find the slope of a line? The slope of a line tells us how something changes over time. If we find the slope we can find the rate of change over that period.Why do we need to find the slope of a line?The slope of a line tells us how something changes over time.
