A line passes through the point (-4,9) and has a slope of 4/5.

Write an equation in point-slope form for this line.

y-9= 4/5 (x+4)

Step-by-step explanation:

You should know that the format for point slope form is y-y1=m(x-x1). So, plug in your coordinate to the equation. It should look like this: y-9=m (x+4). One thing you should know is if your coordinate is a negative number, it becomes a positive in point slope form. Next, plug in your slope to the equation. This is your final y-9= 4/5 (x+4). Hope this helped!
