Hello!
To write this equation, let's first find the slope using the formula
.
Plug in the values
Now solve to find our slope.
<u />Your slope is -3.
Plug that into slope-intercept equation.
Now we find our y-intercept by plugging in a y-coordinate for the y value in the equation. I'll use 6
Your y-intercept is -2.
Your equation is y = -3x - 2
