y=-2x
Explanation
You could find the slope of line going through the points (2,-4) and (-1,2). It is
slope is -6/3 or -2
So the line is
Now plug in one of the points and the slope into point slope form and find the line
y+4=-2(x-2) or
y+4=-2x+4 so
y=-2x
Check it by making sure BOTH points are on the line. Plug the values into the equation you found for the line.
-4=-2(2)
2=-2(-1)
x = 2
What is the equation of the vertical line passing through (-5,-2)
Points: (2, 2) and (3, 1) Slope: -1 Equation: y = -x+4
Points: (1, 5) and (2, 7) Slope: 2 Equation: y = 2x+3
Points: (3, 2) and (-9, 6) Slope: -1/3 Equation: 3y = -x+9
The formula for a line is: Y = mX + b
The equation is x = 2
x = 2
Points: 0 2 and 6 0 Equation: y = -1/3x+2
y = -1.125x + 2.25
y = 4
What is the equation of the vertical line passing through (-5,-2)
y = 2.25x -6
Points: (2, 2) and (3, 1) Slope: -1 Equation: y = -x+4
If you mean of points of (3, -4) and (5, 1) then the equation works out as 2y=5x-23
Points: (1, 5) and (2, 7) Slope: 2 Equation: y = 2x+3
Points: (0, 3) and (5, 23) Slope: 4 Equation: y = 4x+3
