Use the slope formula [tex] \frac{y2-y1}{x2-x1} [/tex] to find the slope. This will be the m in y=mx+b. The b will be your y intercept. Find this by substituting your coordinates for x and y of your now y=mx+b. If you are looking for the answer rather than how to do it, it is y=-[tex] \frac{2}{3} [/tex]x+[tex] \frac{1}{3} [/tex]. This is by my math. Try it yourself.
