A line with slope of zero is horizontal. A line with no slope is vertical because slope is undefined on a vertical line.
find equation of the line. write equation in slope intercept form. (5,5) parallel line (3,13) and (12,13)
The lines below are perpendicular. If the slope of the green line is -1, what is the slope of the red line?
If a line has a slope m then a line perpendicular to it has a slope -1/m ( negative inverse). For example if a line has slope positive 2, its perpendicular has slope -1/2
To find the slope of a perpendicular line, take the negative reciprocal of the slope of the given line. (Flip the top and bottom of the fraction and change the sign.) The slope of 3 can be written as 3/1. The slope of a line that is perpendicular is -1/3.
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
You can write it either in standard form (ax + by = c) or in slope-intercept form (y = mx + b)
The slope of a line on a graph can be zero, or any positive or negative real whole number or fraction or decimal.
That's right. If a system of equations has a solution, then their graphs intersect, and the point where they intersect is the solution, because it's the point that satisfies each equation in the system. Straight-line graphs with the same slope are parallel lines, and they never intersect, which is another way of saying they have no solution.
Two lines with the same slope and y-intercept look like one single line. The "system" of equations consists of the same equation twice. The lines coincide at every point, which means there are an infinite number of solutions.
point-slope formula and finding the slope of the line.
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.
2x+y=3 is a line that has a -2 slope and 6x=9-3x is a vertical line. They will cross at one place. That is (1,2)

If they have the same slope, then there are two possibilities. First say they have the same slope and different y intercepts. This means they are parallel lines and there is no intersection. The solution is the empty set or we say there is no solution.If the y intercept is the same, then the two equations represent the same line. In this case there is an infinite number of solutions.
A line with slope of zero is horizontal. A line with no slope is vertical because slope is undefined on a vertical line.
