4b.) write an equation using point-slope form with a slope of 2.3 and goes
through the point: (4.5, -3.2)

Step-by-step explanation:

So the point-slope formula looks like this:

= any y point on the line

= any x point on the line

= the slope

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

So we can just plug those values into the equation:

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

i think it is 70
