The equation of the line plotted in the graph with the similar triangles on the coordinate plane is y equal to three-fourths x.
Symbolically, it can be written as,
[tex]y=\dfrac{3}{4}x[/tex]
The equation of the line is the way of representation of a line in the equation form.
The equitation of the lines represents the line by the set of points on which the line lies or passes through in the coordinate system.
[tex]y=mx+c[/tex]
Here, (m) is the slope of the line and (c) is the y intercept.
The similar triangles on the coordinate plane to determine the equation for the given line. The line and the triangle is graphed in the image attached below.
The line passes from origin point (0,0). The coordinate points on the line say P are (4,3) as shown in the image. Thus, for this the slope of the line can be given as,
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}\\m=\dfrac{3-0}{4-0}\\m=\dfrac{3}{4}[/tex]
The equation of the line for 3/4 slope is,
[tex]y=\dfrac{3}{4}x[/tex]
Hence, the equation of the line plotted in the graph with the similar triangles on the coordinate plane is,
[tex]y=\dfrac{3}{4}x[/tex]
