Answer:


y+3.2=2.3(x-4.5)

Explanation:

So the point-slope formula looks like this:
y-y_1=m(x-x_1)


y_1 = any y point on the line


x_1 = any x point on the line


m = the slope

And hey, look, we're already given all that information!

So we can just plug those values into the equation:


y+3.2=2.3(x-4.5)

(*note: It's a +3.2 because 3.2 was negative in the first place, and -(-x) = +x)
