The equation of the line that cuts through (0,5) and (1,2) is y = -3x + 5
<h3><u>Solution:</u></h3>Given that we have to find equation of the line that cuts through (0,5) and (1,2)
The equation of line passing through points and
is given as:
Where "m" is the slope of line
Let us first find slope of line
<em><u>The slope of line is given as:</u></em>
<em><u>Thus the required equation of line is:</u></em>
Thus the equation of line is found
The required piecewise function that represents the graph is given as:
The graph consists of 3 lines with different equations and slopes. In order to determine the function it represents, we will create a piecewise function.
For the line crossing the negative x-axis
Using the coordinate points (-4, 2) and (-2, -4)
Slope = -6/2
Slope = -3
2 = -3(-4) + b
2 - 12 = b
b = -10
The equation of the line will be y = -3x-10
For the line crossing the negative y-axis
Using the coordinate points (-2, -4) and (2,-2)
Slope = 2/4
Slope = 1/2
-2 = 1/2(2) + b
-2 - 1 = b
b = -3
The equation of the line will be y = -1/2x-3
For the line crossing the positive x-axis
Using the coordinate points (2, -2) and (3, 0)
Slope = 2/1
Slope = 2
0 = 2(3) + b
0 - 6 = b
b = -6
The equation of the line will be y = 2x-6
The required piecewise function that represents the graph is given as:
