Answer:

Equation: y = 3x + 2

Step-by-step explanation:

Choose two points from line

Chosen Points: (1, 5) (1.5, 6.5)

[ Find Slope ]


\bold{\mathrm{Slope}=(y_2-y_1)/(x_2-x_1)}


\bold{\left(x_1,\:y_1\right)=\left(1,\:5\right),\:\left(x_2,\:y_2\right)=\left(1.5,\:6.5\right)}


\bold{m=(6.5-5)/(1.5-1)}


\bold{m \ = \ 3}

[ Find Y - Intercept ]


\bold{y=3x+b}


\bold{\mathrm{Plug\:in\:}\left(1,\:5\right)\mathrm{:\:}\quad \:x=1,\:y=5}


\bold{5=3\cdot \:1+b}

Isolate B


\bold{5=3\cdot \:1+b}


\bold{b \ = \ 2}

[ y = 3x + 2 ]
