What is the equation of the blue line?

zaharov [31]

Answer: <em>y = 3x + 2</em>

Step-by-step explanation:

$\dfrac{x-x_{1} }{x_{2} -x_{1} } =\dfrac{y-y_{1} }{y_{2} -y_{1} }\\$

<em>Let's choose two arbitrary points on the graph.</em>

<em>For example, let these be points with coordinates (1, 5) and (2, 8).</em>

<em>Substitute the coordinates of these points into the above formula and derive the equation of a straight line.</em>

$\dfrac{x-1}{2-1} =\dfrac{y-5}{8-5}\\\\\dfrac{x-1}{1} =\dfrac{y-5}{3}\\\\3(x-1)=y-5\\3x-3=y-5\\y=3x-3+5\\y=3x+2$
