Answer:
Step-by-step explanation:
Slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept. Since we are given slope, we can plug that into m, and use the given point to find the y-intercept.
[plug in (8,9)]
[multiply]
[subtract both sides by 6]
Now that we have b, we can complete the equation to .
