Plot the y-axis, which is the b in the y=mx+b in the slope intercept equation. Then, you put your slope and plot the line.
If the slope of a line is m then the slope of an altitude to that line is -1/m.
To ascertain the slope of a line two sets of coordinates are required or other information that enables the slope to be determined. Without this extra information an answer to this question cannot be provided.
The slope of both lines will be the same.
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.
There are a couple ways to determine the equation of a line without graphing. How to proceed depends on what you know about the line. Do you know a point, (x1, y1), and slope, m? Then use the point-slope formula, Do you know two points on the line, say (x1, y1) and (x2, y2)? Then use the two-point formula,
You must find the slope, if it is positive, then the line is always increasing. If it is negative, then the line is always decreasing.
If you have an equation that looks like y=mx+b then the m is the slope. If you have two points then you use the formula Y2-Y1/X2-X1
By substitution
The y-intercept, together with the slope of the line, can also be used in graphing linear equations. The slope and y-intercept of a line can be obtained easily by inspection if the equeation of the line is of the form y=mx+b where m is the slope and b is the y-intercept.
Rate can be the slope of a line when some variables are graphed. Ex: When graphing distance vs time for a moving object the slope of the line is the rate.
When y = 7x +4 the y intercept is 4 and the slope is 7
When you graph a line using only the slope and a point, you start by graphing the point.
For a positive number, as the slope(y=mx+b where m is the slope) gets greater in value, the line gets steeper when plotted on a graph. For a negative number, as the slope(y=mx+b where m is the slope) gets greater in value, the line gets less steep when plotted on a graph.
None. Different people prefer different ways of working.
It depends on which calculator! If the data is linear, you can estimate the slope of the line and the y-intercept from graphing the data. By graphing the data, you will be able to tell if it forms a straight line or not.
Plot the y-axis, which is the b in the y=mx+b in the slope intercept equation. Then, you put your slope and plot the line.
