There are 3 forms to write the equation of a line
point slope y-y1=m(x-x1)
for this form you need one set of points and you plug them into x1 and y1
and you need the slope which you plug into m
The formula for a line is: Y = mX + b
You cannot define a line with a single point (a single point only defines itself). You need two points to define a line (and therefore to write the equation for it).
Points: (20, 18) and (35, 6) Slope: -4/5 Equation: y = -4/5x+34
In coordinated geometry the points on a straight line will determine its equation.
Points: (5, -2) and (4, 3)Slope: -5Equation: y = -5x+23
Write the equation of the line that passes through the points (3, -5) and (-4, -5)
The formula for a line is: Y = mX + b
Actually, two separate points are enough to determine the line.
You cannot define a line with a single point (a single point only defines itself). You need two points to define a line (and therefore to write the equation for it).
No, you need either two points, one point and a slope, one point and a y-intercept, or a y-intercept an a slope. You can also write the equation of a line with an equation of another line but you would have to know if it is parallel or perpendicular.
Slope-intercept form
Points: (-3, -4) and (6, -1) Slope: 1/3 Equation: 3y = x-9
It works out as: y = 2x+1
Points: (20, 18) and (35, 6) Slope: -4/5 Equation: y = -4/5x+34
In coordinated geometry the points on a straight line will determine its equation.
Since the slope of the line is 0, then the line is a horizontal line, and since the y-coordinates of the two points are 0, then the line lies on the x-axis. Thus, the equation of the line is y = 0.
