A vertical line does not have a slope - negative or positive. It is not defined.

A vertical line has no y intercept and, if its equation is x = c (for some number c), then the x-intercept is (c, 0).

How do you find the slope intercept of a vertical line?

A vertical line on a graph has infinite slope and no y-intercept. Its equation is [ x = a number ]. The number is the line's x-intercept.


How do you find the slope intercept and standard forms of a line when the slope is undefined and you are given the coordinates 2 and 4?

When the slope is undefined, you know the line has to be vertical. Vertical lines only have an x in their equations. When you have the coordinates (2,4) with a vertical line, the equation for the slope intercept AND standard form would be the same thing: x=2


How do you find slope intercept form?

the formula for slope-intercept form is y=mx+b. in the equation mx is the slope and b is the y-intercept.


Find the slope and y-intercept of y subtract 2 equals negative 3x?

y-2 = -3x ok you need to rewrite this in the form of y = mx+c where m = slope and c = y intercept y = -3x+2 slope = -3 y intercept = 2


What is the slope intercept form of the line that has a slope of negative 3 and contains the points of 4 and negative 5?

The slope intercept form is: y=mx+b where m is the slope and b is the y-intercept. Since you already know the slope, you can plug that into the equation. y=-3x+b The only thing left to do is to find out what b is. To do this, plug the x and y value of the point it goes through into the equation and solve for b. Good luck.


Find the equation of the line in slope intercept form slope 2 y-intercept -8?

The slope intercept form is y=mx+b where m is the slope and b is the y intercept y=2x-8.


What is a line in slope-intercept form?

A line in slope-intercept form is: y = mx + b m is the slope of the line, and b is the y-intercept. To find the slope, find any two coordinates, and divide the difference in y-values by the difference in x-values; to find the y-intercept, find the value of y where x = 0.


How do you find a slope to a equation?

the slope formula is y=mx+b slope-intercept form of an equation of a line. where m=slope and b=the y-intercept


How would you find the equation of a line if you were given the slope and the y-intercept?

y = {slope}x + {y intercept}


How do you find the slope and y-intercept of y equals 31x plus 4?

slope = 31 and intercept = 4


How do you find the slope when you have the y-intercept and one point?

Draw a straight line from the intercept to the given point. Under this line form a right angle triangle with the line being its hypotenuse. The vertical units of the triangle divided by the horizontal units will be the slope of the straight line.


How do you find slope intercept form when given coordinates?

Use: (y2 -y1)/(x2 -x1) to find the slope. Use: y -y1 = m(x -x1) to find the slope intercept equation whereas m is the slope.
