Answer:
y=3/5x-1
Step-by-step explanation:
The formula you need to find this would be
(y-y1)=m(x-x1)
The y1 is your y point.
The x1 is your x point.
m is your slope.
Start by plugging in your numbers that they provide you.
(y-8)=3/5(x-15)
Now you need to distribute the slope to the terms inside the parenthesis next to it.
3/5(x)=3/5x
3/5(-15)= -9 Now you put those back into the equation.
(y-8)=3/5x-9
At this point you can get rid of the parenthesis around the y-8 since it is basically saying to take the term times 1.
To get y alone we not need to add 8 to both sides.
y-8=3/5x-9
+8 +8
y=3/5x-1
