Answer:
y=-\frac{2}{3}x+3
Explanation:
![y=mx+b](https://img.qammunity.org/2022/formulas/mathematics/high-school/vx6rl06zg4fbsmfy3o2eukr7b78jm4ngki.png)
There are 4 variables in this equation, and 3 of them are already given. We already have the slope and the (x, y) of a known point. Plug those 3 into the equation and solve for b:
![7=-(2)/(3)(-6)+b\\7=4+b\\b=3](https://img.qammunity.org/2022/formulas/mathematics/high-school/911emya8w8uj5adsleuz0qzmeoxr995ax8.png)
Now, with the slope and the y-intercept, you can write the equation of the line:
![y=mx+b\\\\y=-(2)/(3)x+3](https://img.qammunity.org/2022/formulas/mathematics/high-school/x64b631ejzkwazbovst3g5uq642vns3i5o.png)
