Answer:

y=\frac{2x}{5}+\frac{24}{5}

Step-by-step explanation:

Hello

to solve this , we can use the point-slope is the general form y-y₁=m(x-x₁) for linear equations. It emphasizes the slope of the line and a point on the line (that is not the y-intercept)

y-y_{0} =m (x-x_{0})\\ \\

Let

m=\frac{2}{5} \\\\P1(-2,4)\\x_{0}=-2\\y_{0} =4\\ \\

replacing

y-4=\frac{2}{5}(x-(-2))\\ \\y-4=\frac{2x}{5}+\frac{4}{5}\\y=\frac{2x}{5}+\frac{4}{5}+4\\y=\frac{2x}{5}+\frac{24}{5}

Have a great day

Valentin [98]
\frac{v-9}{10v+6}=11 \\\\ 11(10v+6)=v-9 \\\\ 110v+66=v-9 \\\\ 110v-v=-9-66 \\\\ 109v= -75 \\\\ \boxed{v=-\frac{75}{109}}
